<p>A thermoplastic elastomer composition which comprises the following ingredients (A) and (B), the (A)/(B) weight ratio being from 5/95 to 95/5. (A): A thermoplastic resin having a melt flow rate of 0.001 to 100 g/10 min and a die swell ratio of from 1.7 to 5.0. (B): A hydrogenated vinylaromatic compound/conjugated diene copolymer satisfying all of the following requirements (i) to (iii): the content of vinylaromatic compound units is 50 wt.% or lower; the proportion of hydrogenated conjugated diene units having a side chain with two or more carbons to all the hydrogenated conjugated diene units in the hydrogenated vinylaromatic compound/conjugated diene copolymer is 60% or higher; and 80% or more of the double bonds of the conjugated diene units contained in the hydrogenated vinylaromatic compound/conjugated diene copolymer have been hydrogenated.</p> |
