PROBLEM TO BE SOLVED: To provide a porous film laminate excellent in terms of pore characteristics, heat-resistant, flexible, and also excellent in terms of handling friendliness and moldability and a method for manufacturing the same.SOLUTION: The provided porous film laminate is a porous film laminate obtained by laminating a porous layer on at least one surface of a substrate wherein the substrate includes a heat-resistant non-woven fabric, wherein the porous layer possesses many punch-through micropores in a state where the average diameter of the micropores is 0.01 to 10 μm, wherein the wrinkling magnitude of the porous film laminate is regulated at a fixed value or below, and wherein no interfacial peeling of the substrate and the porous layer is induced during a tape peeling test. |
