PROBLEM TO BE SOLVED: To provide a film having a high rigidity which has not conventionally been achieved, being excellent in dimensional stability under a high temperature, and in addition, being excellent in transparency after heating, and a molding workability in a wide temperature range as well. SOLUTION: This laminated film has fifty layers or more which are formed of layers made of a thermoplastic resin A and layers made of a thermoplastic resin B. In the laminated film, anαsoftening temperature in a dynamic viscoelasticity measurement is observed in a range from (theαsoftening temperature of the thermoplastic resin B+10)°C to (theαsoftening temperature of the thermoplastic resin A-10)°C, and also, two or more melting points exist.
