(57) [Problem] To prevent bleeding of process oil on the surface of a molded product even after a lapse of time in a high temperature state after molding. Further, the present invention provides an olefin-based thermoplastic elastomer excellent in moldability and a molded article thereof. (A) A specific crystalline ethylene polymer 5 30% by weight, (B) 20 to 70% by weight of an ethylene / α-olefin (. Non-conjugated polyene) copolymer rubber, (C) High stereoregularity propylene having a stereoregular mesopentad fraction [mmmm] of 95% or more 5 to 40% by weight of polymer, (D) 10 to 50% by weight of process oil ((A), (B), (The sum of (C) and (D) is 100% by weight). |
