PROBLEM TO BE SOLVED: To provide a multilayered laminate usable as an industrial material excellent in the balance of characteristics such as chemical resistance, barrier properties, dimensional and stability. SOLUTION: The multilayered laminate is constituted by directly bonding a polyamide elastomer layer, which is obtained by the coextrusion of a polyamide elastomer (A) with an amino group concentration of 10-100 mmol/kg and a fluoroplastic resin (B), and a fluoroplastic resin layer. For example, the polyamido block of the polyamide elastomer is constituted of polyamide 11, polyamide 12 or polyamide 612. As the polyamide elastomer, a block copolymer composed of the polyamide block and a polyether block is preferable. Further, it is preferable that the polyamide block of the polyamide elastomer and another block are bonded by an amide bond. COPYRIGHT: (C)2007,JPO&INPIT
