PROBLEM TO BE SOLVED: To provide a manufacturing method of thermosetting resin moldings with reduced unsaturated monomer and oligomer components which remain in the moldings and cause an odor, and suitable for using in housings, panels, and various parts for a bathtub, a supply or receiving water tank, or the like. SOLUTION: In a manufacturing method of a thermosetting resin moldings in which at least a curing agent is compounded in a liq. resin prepared by dissolving an unsaturated polyester resin in an unsaturated monomer having at least a polymerizable double bond in the molecule and heated for curing reaction, the heat curing temp. is set in a range between a temp. at which the quantity of the curing agent decreases to half in 10 hrs. (decomposition temp.) and a temp. which is the decomposition temp. +20 deg.C.
