PROBLEM TO BE SOLVED: To provide a laminated film with an adhesive for electric materials, which is excellent in adhesiveness at a low temperature while retaining adhesiveness at room temperature to a high temperature, is excellent in temporary bonding before heat bonding of products in forming and is high in mass-productivity. SOLUTION: The laminated film with an adhesive for electric materials comprises a substrate made of a plastic film and at least one adhesive layer provided onto at least one face of the substrate, wherein at least the surface layer of the adhesive layer has a polyester-based hot-melt adhesive containing a crystalline polyester based resin and an amorphous polyester based resin in a mass ratio of 80:20-99:1.
