The present invention relates to a process for producing a resin composite molded article comprising bonding a molded article (A) of a resin A which contains a polymer containing an alicyclic structure and a molded article (B) of a resin B to produce a resin composite molded article, the bonding including a step 1 of applying at least one activation treatment selected from plasma application, excimer ultraviolet irradiation, and corona discharge to the bonding surface of the molded article (A), followed by a treatment with a silane coupling agent (A), a step 2 of applying at least one activation treatment selected from plasma application, excimer ultraviolet irradiation, and corona discharge to the bonding surface of the molded article (B), and a step 3 of superposing the bonding surface of the molded article (A) on the bonding surface of the molded article (B), and press-bonding the bonding surfaces. According to the present invention, a resin composite molded article having excellent peeling resistance can be produced by bonding the molded article of the resin A which contains a polymer containing an alicyclic structure and the molded article of the resin B at a temperature below the glass transition temperature of the resins without using an adhesive.
