<P>PROBLEM TO BE SOLVED: To provide a laminate which is obtained by sticking a polyimide resin film to a polyolefin resin film without using an adhesive, from which foreign matter, a residual solvent or the like does not ooze out, and which is excellent in strength, heat resistance, electrical insulation properties, chemical resistance and heat sealability. <P>SOLUTION: The laminate is obtained by layering the polyimide resin film on the polyolefin resin film. In at least a part of the polyimide resin film and the polyolefin resin film, bonding is formed between an atom in the polyimide resin film and an atom in the polyolefin resin film, and the polyimide resin film and the polyolefin resin film are stuck to each other without interposing adhesive. <P>COPYRIGHT: (C)2013,JPO&INPIT |
