PROBLEM TO BE SOLVED: To provide a case for a multi-purpose card or the like provided with the feeling of a high grade, no change of properties caused by temperature and time used, and the high stability of a shape and easy to execute a correct sticking operation, and an economical manufacturing method. SOLUTION: The case for the card or the like of this invention is constituted of a film of an ethylene copolymerization polypropylene resin in which at least a part of the film is laminated more than two layers, a pocket body in which a peripheral edge portion except an opening portion is bonded integrally by welding is bonded to a release paper through a pressure sensitive adhesive layer provided on the outer surface of the film in a large area side, and is laid disposingly on the surface of the release paper by applying a pressure sensitive adhesive on the surface on which the corona discharge treatment of the film of the ethylene copolymerization polypropylene resin has been executed, and then a laminated body is formed by disposingly laminating the desired number sheets of the films having the same quality as the above film in desired positions, and subsequently, by using a trimming die of a desired shape provided with the heated edge of a blade, this case is manufactured by welding the laminated portion of the film of the laminated body and by fusing the peripheral edge of the film portion at the same time.
