본 발명의 일 실시형태는 열가소성 엘라스토머 조성물 또는 그 성형체에 관한 것으로, 해당 열가소성 엘라스토머 조성물은, 에틸렌, 탄소수 3∼20의 α-올레핀 및 비공액 폴리엔 유래의 구성 단위를 포함하는, 에틸렌·α-올레핀·비공액 폴리엔 공중합체(A) 100질량부와, 결정성 폴리올레핀(B) 1∼100질량부와, 25℃에서의 점도(ASTM D 445-46T의 측정 방법에 준거)가 10만cSt 이하인, 폴리오가노실록세인(C) 0.1∼20질량부와, 고급 지방산 아마이드(D) 0.1∼3질량부를 포함한다. One embodiment of the present invention relates to a thermoplastic elastomer composition or a shaped article thereof. The thermoplastic elastomer composition includes 100 parts by mass of an ethylene/α-olefin/non-conjugated polyene copolymer (A) including constituent units derived from ethylene, a C3-C20 α-olefin and a non-conjugated polyene; 1 to 100 parts by mass of a crystalline polyolefin (B); 0.1 to 20 parts by mass of a polyorganosiloxane (C) having a viscosity at 25°C (measured by a method in accordance with ASTM D 445-46T) of 100,000 cSt or less; and 0.1 to 3 parts by mass of a higher fatty acid amide (D).
