    • PROBLEM TO BE SOLVED: To provide a composite member which is excellent in moldability in injection molding or the like, has appropriate softness (hardness), and is especially suitable for glass run channel in an automobile. SOLUTION: The composite member comprises a first molding part formed by molding an olefin based thermoplastic elastomer composition (A) containing a crystalline thermoplastic resin (a-1) of 5-95 pts.wt., an ethylene-α-olefin based copolymer rubber (a-2) of 5-95 pts.wt. and a softener (a-3) of 0-200 pts.wt. and a second molding part which is joined to at least a part of the surface and/or the cross section of the first molding part, is formed by extrusion molding and formed by molding an olefin based thermoplastic elastomer composition (B) containing a crystalline thermoplastic resin (b-1) of 5-95 pts.wt., an ethylene-alpha-olefin based copolymer rubber (b-2) of 5-95 pts.wt. and a softener (b-3) of 0-200 pts.wt.
