- the first space 510 is a space to be exhausted later
- the second space 520 is a space used for exhausting the first space 510.
- the partition 420 has a first end side in the length direction of the second glass substrate 300 (left and right direction in FIG. 4) from the center of the second glass substrate 300 so that the first space 510 is larger than the second space 520. (The right end side in FIG. 4).
- the partition 420 includes a wall portion 421 and a pair of blocking portions 422 (a first blocking portion 4221 and a second blocking portion 4222).
- the wall portion 421 is formed along the width direction of the second glass substrate 300 (the vertical direction in FIG. 4). However, both ends in the length direction of the wall portion 421 are not in contact with the frame body 410.

- the exhaust port 700 is a hole that connects the second space 520 and the external space.
- the exhaust port 700 is used for exhausting the first space 510 through the second space 520 and the ventilation path 600. Accordingly, the ventilation path 600, the second space 520, and the exhaust port 700 constitute an exhaust path for exhausting the first space 510.
- the exhaust port 700 is formed in the second glass substrate 300 so as to connect the second space 520 and the external space. Specifically, the exhaust port 700 is located at a corner portion of the second glass substrate 300.
- the gas adsorber 60 is disposed in the first space 510.
- the gas adsorber 60 has a long flat plate shape, and the second glass substrate 300 in the width direction on the second end side (left end side in FIG. 5) in the length direction of the second glass substrate 300. It is formed along. That is, the gas adsorber 60 is disposed at the end of the first space 510 (vacuum space 50). In this way, the gas adsorber 60 can be made inconspicuous. Further, the gas adsorber 60 is located away from the partition 420 and the ventilation path 600. For this reason, when the first space 510 is exhausted, the possibility that the gas adsorber 60 prevents the exhaust can be reduced.
- the gas adsorber 60 is used for adsorbing unnecessary gas (residual gas or the like).
- the unnecessary gas is, for example, a gas released from the frame body 410 and the partition 420 when the frame body 410 and the partition 420 are heated.

- a getter is a material that has the property of adsorbing molecules smaller than a predetermined size.
- the getter is, for example, an evaporation type getter.
- the evaporable getter has a property of releasing adsorbed molecules when the temperature is higher than a predetermined temperature (activation temperature). Therefore, even if the adsorption ability of the evaporable getter is reduced, the adsorption ability of the evaporable getter can be recovered by heating the evaporable getter to the activation temperature or higher.
- the evaporative getter is, for example, a zeolite or an ion exchanged zeolite (eg, a copper ion exchanged zeolite).
- the gas adsorber 60 includes the getter powder.
- the gas adsorbent 60 is obtained by a liquid containing getter powder (for example, a dispersion obtained by dispersing getter powder in the liquid, or by dissolving the getter powder in the liquid. It is formed by applying and solidifying a solution.
- the gas adsorber 60 can be made small. Therefore, the gas adsorber 60 can be disposed even if the vacuum space 50 is narrow.
- the plurality of spacers 70 are used to maintain the interval between the first glass substrate 200 and the second glass substrate 300 at a predetermined interval. That is, the plurality of spacers 70 are used to maintain the distance between the first glass panel 20 and the second glass panel 30 at a desired value.
- the plurality of spacers 70 are arranged in the first space 510. Specifically, the plurality of spacers 70 are arranged at intersections of virtual rectangular grids. For example, the interval between the plurality of spacers 70 is 2 cm. However, the size of the spacers 70, the number of the spacers 70, the interval between the spacers 70, and the arrangement pattern of the spacers 70 can be selected as appropriate.
- the spacer 70 has a cylindrical shape having a height substantially equal to the predetermined interval.
- the spacer 70 has a diameter of 1 mm and a height of 100 ⁇ m.
- Each spacer 70 may have a desired shape such as a prismatic shape or a spherical shape.
- the spacer 70 is formed using a transparent material. However, each spacer 70 may be formed using an opaque material as long as it is sufficiently small.
- the material of the spacer 70 is selected so that the spacer 70 is not deformed in a first melting process, an exhaust process, and a second melting process, which will be described later.
- the material of the spacer 70 is selected to have a softening point (softening temperature) that is higher than the first softening point of the first thermal adhesive and the second softening point of the second thermal adhesive.
- Such a temporary assembly 100 is subjected to the predetermined processing in order to obtain the assembly 110.
- the first space 510 is evacuated to the vacuum space 50 through the ventilation path 600, the second space 520, and the exhaust port 700 at a predetermined temperature (exhaust temperature) Te.

- the exhaust pipe 810 is joined to the second glass substrate 300 so that the inside of the exhaust pipe 810 and the exhaust port 700 communicate with each other.
- a seal head 820 is attached to the exhaust pipe 810, whereby the suction port of the vacuum pump is connected to the exhaust port 700.

- the first space 510 is exhausted through the ventilation path 600, the second space 520, and the exhaust port 700 for a predetermined time (exhaust time) te at the exhaust temperature Te (see FIG. 9).
- the exhaust temperature Te is set higher than the activation temperature of the getter of the gas adsorber 60 (for example, 350 ° C.) and lower than the first softening point and the second softening point (for example, 434 ° C.).
- the exhaust temperature Te is 390 ° C.
- the frame 410 and the partition 420 are not deformed. Further, the getter of the gas adsorber 60 is activated, and molecules (gas) adsorbed by the getter are released from the getter. Then, the molecules (that is, gas) released from the getter are discharged through the first space 510, the ventilation path 600, the second space 520, and the exhaust port 700. Therefore, in the exhaust process, the adsorption capacity of the gas adsorber 60 is recovered.

- the exhaust time te is set to 120 minutes.
- the second melting step is a step of forming the seal 40 that surrounds the vacuum space 50 by deforming the partition 420 to form the partition wall 42 that closes the ventilation path 600.

- the second melting temperature Tm2 and the second melting time tm2 are set so that the second thermal adhesive softens and the partition wall 42 that blocks the air passage 600 is formed.
- the lower limit of the second melting temperature Tm2 is the second softening point (434 ° C.).
- the second melting temperature Tm2 is higher than the first melting temperature (440 ° C.) Tm1.
- the second melting temperature Tm2 is set to 460 ° C.
- the second melting time tm2 is, for example, 30 minutes.
- the vacuum space 50 is separated from the second space 520. Therefore, the vacuum space 50 cannot be exhausted with the vacuum pump. Until the second melting step is completed, the frame body 410 and the partition wall 42 are heated, and thus gas may be released from the frame body 410 and the partition wall 42. However, the gas released from the frame 410 and the partition wall 42 is adsorbed by the gas adsorber 60 in the vacuum space 50. Therefore, the vacuum degree of the vacuum space 50 is prevented from deteriorating. That is, it is prevented that the heat insulation of the glass panel unit 10 deteriorates.
- the gas adsorber 60 can sufficiently adsorb the gas released from the frame body 410 and the partition wall 42 in the second melting step. That is, it is possible to prevent the gas adsorber 60 from sufficiently adsorbing the gas released from the frame body 410 and the partition wall 42 and deteriorating the vacuum degree of the vacuum space 50.
- the first space 510 is exhausted through the ventilation path 600, the second space 520, and the exhaust port 700 continuously from the exhaust step. That is, in the second melting process, the partition 420 is deformed while the first space 510 is evacuated through the ventilation path 600, the second space 520, and the exhaust port 700 at the second melting temperature Tm2, and the ventilation path 600 is changed. A partition wall 42 for closing is formed. This further prevents the vacuum degree of the vacuum space 50 from being deteriorated during the second melting step. However, in the second melting step, it is not always necessary to exhaust the first space 510 through the air passage 600, the second space 520, and the exhaust port 700.
