。(Problems to be Solved by the Invention) In such cases, variations are often observed in the adhesive strength (peel strength of the fused portion) (adhesion strength is specifically measured as shown in Figure 3). In extreme cases, it was too weak to be of practical use. In Fig. 3, (1) is a porous membrane of fluororesin such as tetrafluoroethylene resin, (2) is a thermoplastic resin member,
(3) is water, (4) is air pressurization, and (5) is a fused portion.

上記に鑑み本発明は上記接着強度のばらつきを解消させ

がその逆よりも接着強度が大きいことがわかった。The present inventors analyzed this layered layer and found that there was a clear difference in adhesive strength between the front and back sides of the film. That is, it was found that the adhesive strength was greater when the surface with larger pores was used as the surface to be fused with the thermoplastic resin than when the other side was used.

This is characterized in that the larger side is heat-sealed as the resin member side.

。この際樹脂部材は熱可塑性に限定されない。In the present invention, as described above, thermal fusion has been described as fusion bonding, but instead of thermal fusion, chemical treatment (melting the component resin with a solvent such as acetone, and melting the molten resin into the pores of the porous membrane) It may also be fusion bonding or adhesion, such as adhesive treatment (adhesive enters into the pores of the porous membrane). At this time, the resin member is not limited to thermoplastic material.
