PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer composition having excellent heat fisibility to both of an olefinic resin and a non-olefinic resin, and a composite molded material composed of the elastomer. SOLUTION: This composition consists of (A) 5-95wt.% of a styrenic block copolymer comprising a block composed of a polymer of styrene or its derivative (a) and a block composed of a homopolymer of isoprene or a copolymer of isoprene and butadiene (b), and the total amount of 1,2-bond content and 3,4-bond content in the isoprene polymer part in the block (b) is >=40wt.% of the whole of isoprene bond units or its hydrogenated substance and (B) 95-5wt.% at least one kind of thermoplastic elastomer selected from the group consisting of a polyester-based elastomer, a polyamide-based elastomer and a polyurethane- based elastomer. |
