PROBLEM TO BE SOLVED: To provide a method by which a composite molded item, such as the injection circuit board, injection molded circuit parts, etc., having a small size can be manufactured with high dimensional accuracy by markedly improving the productivity. SOLUTION: In a method for manufacturing a composite molded item, the item is manufactured in such a way that, after a molded aggregate composed of a plurality of single base molded bodies which become the skeletons of the composite molded item is formed by injection molding resin, cutting grooves for hand breaking are formed along dividing lines and plated metallic wiring patterns are selectively formed on the surface of the aggregate. Then finally the aggregate is divided into the single base molded bodies, by breaking the aggregate by hand along the cutting grooves.
