is decomposed by combustion to become carbon dioxide gas, and this carbon dioxide gas is absorbed inside the layer of inorganic adhesive 12 to form pores.
しかし、このような空孔は大きさが僅かであり、しかも
この時には無機質接着剤１２による接着力が発生してい

い。However, since such pores are small in size and the adhesive force of the inorganic adhesive 12 is generated at this time, there is no fear that the adhesive force of the inorganic adhesive 12 will be impaired.
このようにして無機質接着剤１２が乾燥硬化されること
により、ランプ５と反射鏡１が無機質接着剤１２で接合

向上する。With the above method, when drying and curing the inorganic adhesive 12 in a heating furnace, the lamp 5 and the reflector 1 are connected to the temporary adhesive 1
Since they are bonded at zero, there is no need to use a jig, and therefore the heat capacity is small and heating efficiency is improved. Therefore, even when heated at about 300° C., the drying and curing time, which conventionally required 12 to 15 minutes, is shortened to 5 to 10 minutes, improving work efficiency.
また、ランプ５と反射鏡１の各組ごとに加熱炉を通過さ
せる治具が不要になり、設備費用が削減され、コスト安
になる。Further, a jig for passing each set of the lamp 5 and the reflecting mirror 1 through the heating furnace is no longer necessary, and equipment costs are reduced, resulting in lower costs.
なお、本発明は上記実施例に制約されるものではない。Note that the present invention is not limited to the above embodiments.

悪影響をおよぼさない有機性接着剤であればよい。That is, in the above embodiment, an ultraviolet curable organic adhesive was used as the temporary adhesive 10, but it is not limited to an ultraviolet curable type, and in short, it is an adhesive that functions as an instant adhesive, and the inorganic adhesive 12 Any organic adhesive may be used as long as it does not decompose when heated and does not adversely affect the electromagnetic action.
また、このため、仮止接着剤１０を注入するタイミング

。Furthermore, in the above embodiment, a case has been described in which the halogen light bulb 5 is joined to the reflecting mirror 1 having a reflecting surface made of a dichroic film, but the present invention is not limited to this. In other words, the lamp is not limited to a halogen bulb, but may also be a regular incandescent bulb, a wedge-base bulb, or a discharge lamp.
In addition to the dichroic film, the reflecting mirror may be a cold mirror or a normal reflecting mirror made of aluminum.

No tools needed. Therefore, the heat capacity during heating is reduced, heating efficiency is improved, drying and curing time is shortened, and work efficiency is improved. Furthermore, since no jig is required for passing through the heating furnace, equipment costs are reduced and costs are reduced. Moreover, since the temporary adhesive used was an organic adhesive, this temporary adhesive would scatter when the heat-resistant adhesive made of inorganic adhesive was heated, which would adversely affect the adhesive function of the heat-resistant adhesive. It has no effect.
