To provide a technique in which a phosphorus compound does not inhibit curing of an addition reaction type silicone-based composition even though the addition reaction type silicone-based composition is in contact with a resin molded product containing the phosphorus compound. An integrated molded product including a thermoplastic resin molded product containing a phosphorus compound, an addition reaction type silicone-based composition, and a member, in which: the thermoplastic resin molded product is in contact with the addition reaction type silicone-based composition; and a pentavalent phosphorus compound is used as the phosphorus compound. The thermoplastic resin molded product preferably contains a polybutylene terephthalate resin in light of heat resistance.
