    摘要： Provided are a multilayer film, a method for producing the multilayer film, and a method for producing a molded body using the multilayer film. The multilayer film: has an adhesive layer; has excellent three-dimensional overlaying formability and adhesiveness after being formed into a three-dimensional overlay; can easily be used when being bonded to an adherend; maintains adhesive strength without breaking or wrinkling in a wide range of range temperatures; and is suitable for forming a vacuum. Specifically, the multilayer film has: an adhesive layer comprising a thermoplastic polymer composition containing a thermoplastic elastomer (A) which is a block copolymer or a hydrogenated product thereof having a polymer block (a1) containing aromatic vinyl compound units and having a polymer block (a2) containing conjugated diene compound units; and a base layer comprising an amorphous resin which has a modulus of elasticity of 2 to 600 MPa at an arbitrary temperature of 110 to 160°C. The tensile elongation at break of the multilayer film at a temperature 5°C lower than the glass transition temperature of the amorphous resin is at least 160%.
