Zusammenfassung:	Disclosed are a thermoplastic elastomer composition and a composite molded body. Specifically disclosed is a thermoplastic elastomer composition containing the following component (A1), component (B1) and component (C1). Component (A1): 70-90% by weight of a propylene polymer unit (α1) obtained in a first step by polymerizing a monomer mainly composed of propylene, and an ethylene copolymer unit obtained in a second step by copolymerizing ethylene with propylene and/or an α-olefin having 4 or more carbon atoms Component (B1): an ethylene-propylene copolymer rubber having a Mooney viscosity (ML1+4, 125° C.) of 20-100 and a weight ratio between the monomer unit derived from ethylene and the monomer unit derived from propylene of from 30/70 to 75/25 Component (C1): an ethylene copolymer as a copolymer of ethylene and an α-olefin having 4 or more carbon atoms.
