PROBLEM TO BE SOLVED: To provide a multilayered molded product excellent in interlaminar adhesiveness and the flexibility of a soft resin layer constituted by laminating a layer comprising a polar resin and a layer comprising a composition containing an isobutylene-based block copolymer. SOLUTION: The multilayered molded product is constituted by laminating the layer comprising the polar resin and the layer comprising a thermoplastic resin composition containing the isobutylene-based block copolymer, which is constituted of a polymer block based on isobutylene and a polymer block comprising a monomer component containing no isobutylene as a main component, and a thermoplastic polyurethane resin.
