Thermoplastic elastomer composition, laminate structure and method for producing said laminate structure

A thermoplastic elastomer composition comprising an acrylic block copolymer (I) and a hydrogenated block copolymer (II), wherein

• the content of the acrylic block copolymer (I) is 70 to 300 parts by mass with respect to 100 parts by mass of the hydrogenated block copolymer (II),
• the hydrogenated block copolymer (II) is a hydrogenated product of a block copolymer (P) including
• at least two polymer blocks (A1) containing structural units derived from an aromatic vinyl compound,
• a polymer block (B1) containing 1 to 100 mass % of structural units (b1) derived from farnesene and 99 to greater than 0 mass % of structural units (b2) derived from a conjugated diene other than farnesene, and
• a polymer block (C1) containing less than 1 mass % of structural units (c1) derived from farnesene, and 1 to 100 mass % of structural units (c2) derived from a conjugated diene other than farnesene, wherein
• the block copolymer (P) includes at least one polymer block (B1) located at a terminal, and the hydrogenation ratio of carbon-carbon double bonds in the polymer block (B1) and the polymer block (C1) is 50 to 100 mol %,
• the mass ratio [(A1)/((B1)+ (C1))] of the polymer blocks (A1) to the total of the polymer block (B1) and the polymer block (C1) is 1/99 to 70/30,
• the mass ratio [(A1)/(B1)] of the polymer block (A1) to the polymer block (B1) is 1/99 to 70/30, and
• the hydrogenation ratio of carbon-carbon double bonds in the polymer block (B1) is 50 to 100 mol %.
