PROBLEM TO BE SOLVED: To provide a resin molded body obtained by bonding two or more members, and having excellent antifouling properties at a bonded portion including a joint. A resin molded body formed by joining two or more members formed of a resin composition comprising at least a polypropylene resin, a silicone-grafted polypropylene, and a silicone oil. The joint portion is partly cut, the Rz of the cut surface is smaller than 5 μm, and the Rsm / Rz is larger than 33, whereby the antifouling property of the joint portion is remarkably improved.
