    摘要: A molded product including a film bonded to a resin frame is produced by a method including: 1) reinforcing the film with a solvent-soluble or solvent-disintegrable reinforcing layer; 2) inserting the reinforced film in an injection mold; 3) feeding a resin to the mold to attach a frame body to the reinforced film while injection molding the resin frame; and 4) treating the resulting injection molded product with a solvent to remove the reinforcing layer. This production process can establish a technique capable of bonding (integrally molding) the film solely to the frame body, regardless of the size of the film. The film may preferably be an expanded porous polytetrafluoroethylene film, and the moisture-permeable resin may preferably be combined with the expanded porous polytetrafluoroethylene film.
