Provided are various molded bodies exhibiting excellent design characteristics, impact resistance, weather resistance, and the like, as well as a graft copolymer and a polyorganosiloxane latex as the starting material. A polyorganosiloxane latex, with the weight average particle diameter (Dw) of the polyorganosiloxane particles being 100-200 nm, and the ratio (Dw/Dn) of the weight average particle diameter (Dw) to the number average particle diameter (Dn) being 1.0-1.7. A polyorganosiloxane-containing vinyl copolymer (g) obtained, in the presence of the latex, by polymerization of one or more vinyl monomers. A graft copolymer (G) obtained, in the presence of the copolymer, by graft-polymerizing one or more vinyl monomers. A thermoplastic resin composition, including the graft copolymer (Ga) and another thermoplastic resin (Ha). A molded body obtained by molding the resin composition. A lamp housing for a vehicular lamp, including the molded body obtained by molding the resin composition. |
