PROBLEM TO BE SOLVED: To provide a film for metallic laminate excellent in mechanical characteristics, enabling thermal pressure adhesion, hardly to change a quality of a laminate-metallic plate depending on operating conditions of the thermal pressure adhesion on a metallic plate, and excellent in moldability and productivity. SOLUTION: A polyester film comprises a polyester resin composition compounded with polyethylene terephthalate or a polyester resin (A) having mainly structure thereof and a resin (B) selected from any of polybutylene terephthalate or a polyester resin having mainly structure thereof or polyethylene 2,6-naphthalate, in which melting point peaks by a differential scanning calorimetry(DSC) after leaving in an atmosphere of 280 deg.C for 10 min exist two or more in ranges from not less than 180 deg.C to less than 280 deg.C, further thickness of the polyester is in a range of 5-100μm and dynamic hardness on the surface of the film is in a range of 0.5-30.0 gf/μm2. |
