A thermoplastic elastomer composition comprising the following components (A) and (B), wherein a weight ratio of the component (A)/the component (B) is from 5/95 to 95/5: (A): a thermoplastic resin, whose melt flow rate is 0.001 to 100 g/10 minutes, and whose die swell ratio is 1.7 to 5.0, and (B): a hydrogenated vinyl aromatic compound-conjugated diene-based copolymer satisfied with all the following conditions (i) to (iii): (i) a content of a vinyl aromatic compound unit is not more than 50% by weight, (ii) a ratio of a hydrogenated conjugated diene unit having a side chain of 2 or more carbon atoms contained in the hydrogenated vinyl aromatic compound-conjugated diene-based copolymer to a total hydrogenated conjugated diene unit contained therein is not less than 60%, and (iii) at least 80% of a double bond of a conjugated diene unit contained in the hydrogenated vinyl aromatic compound-conjugated diene-based copolymer is hydrogenated. |
