Abstract: Provided is a method of manufacturing a joined body, each of which provides satisfactory molding processability and can achieve both a satisfactory appearance and joining strength at a joining portion. The method of manufacturing a joined body includes injecting a thermoplastic elastomer, after melting of the thermoplastic elastomer, into a mold in which a molded body (I) is placed, to thereby integrate a molded body (II) derived from the thermoplastic elastomer and the molded body (I) with each other, the molded body (I) containing a filler, the filler having an arithmetic average particle diameter of from 1 μm to 5 μm.

Abstract: Provided is a thermoplastic elastomer composition for a weather strip material which is used for obtaining a molded product which has excellent adhesiveness to both a thermoplastic elastomer adherend and a crystalline ethylene resin adherend and also has excellent heat resistance at a fused portion. The thermoplastic elastomer composition for a weather strip material according to the disclosure contains: an ethylene-α-olefin copolymer rubber (A); an α-olefin crystalline thermoplastic resin (B) having a melting point of 140° C. or higher; an olefin block copolymer (C) obtained by hydrogenating a block copolymer which has a conjugated diene polymer block with a 1,2-vinyl bond content of 25 mol % or less at both ends and also has a conjugated diene polymer block with a 1,2-vinyl bond content of more than 25 mol % in the middle; and a crystalline ethylene resin (D).
