It is fixed to. In addition, a plurality of fixing portions S are formed at the contact portion between the inner side surface 4 a of the second side plate 4 and the side surface 2 a of the core 2 so as to be spaced apart from each other around the core of the core 2. The fixing portion S is a heat-sealed portion formed by melting and solidifying at least one of the side surface 2a of the core 2 and the inner side surface 4a of the second side plate 4 by laser irradiation, for example.

These may be used alone or in combination of two or more.

  Examples of the packing sheet include aluminum foil, aluminum vapor deposited film, fine barrier AT (polyester film vapor-deposited aluminum oxide, trade name, manufactured by Reiko Co., Ltd.), Tech Barrier S, Tech Barrier T, and Tech. Barrier H, Tech Barrier V (silica vapor deposited film, trade name manufactured by Mitsubishi Chemical Kojin Pax Co., Ltd.), Fine Barrier AT (trade name manufactured by Reiko Co., Ltd.) and B-PE (black polyethylene) film And a dry laminate product of a film obtained by coating a light-shielding ink on OPP (biaxially stretched polypropylene film) and VMCP (uniaxially stretched polypropylene film on which aluminum is deposited) is available. The dry laminate is an adhesive applied between two films, thermocompression bonded at a temperature of about 40 to 60 ° C., pre-aged at room temperature for about 24 to 60 hours, and then at about 30 to 50 ° C. for 12 to 12 ° C. This is the work of performing this aging for about 36 hours.

Moisture permeability of the packaging sheet, for example 0.02~4.5g / (24h · ^{m 2)} a but, more preferably ^{0.05~4.3g / (24h · m 2)} , 0. particularly preferably from ^{10~4.0g / (24h · m 2)} , very preferably from ^{0.15~3.5g / (24h · m 2)} , 0.20~3.0g / ( 24 h · m ² ) is very particularly preferred, and 0.30 to 2.0 g / (24 h · m ² ) is very particularly preferred. When the moisture permeability is less than 0.02 g / (24 h · m ² ), the availability is poor, and when it exceeds 4.5 g / (24 h · m ² ), the edge fusion of the photosensitive element is inferior. The moisture permeability here is JISK
