A thermoplastic elastomer composition comprising the following components (a) to (c), characterized in that the proportions of the components (a) and (b) are 20 to 80 wt% and 20 to 80 wt% respectively based on the sum total of the components (a) and (b) and the amount of the component (c) is 1 to 300 parts by weight per 100 parts by weight of the sum total of the components (a) and (b); sheets made from the composition; and laminates comprising the sheets: (a) a block copolymer represented by the general formula (I) and having a weight-average molecular weight of 80,000 to 1,000,000 and/or a hydrogenated block copolymer obtained by hydrogenating the above block copolymer: A(B-A)n and/or (A-B)n (I) [wherein A is a polymer block of a vinyl aromatic hydrocarbon; B is an elastomeric polymer block; and n is an integer of 1 to 5], (b) a softener for hydrocarbon rubbers, and (c) an olefin resin. |
