An object is to provide a manufacturing method of a
fiber-reinforced resin that significantly reduces a resin
filling defect on the surface and surface irregularity caused by a
temperature difference between a molding temperature (curing temperature) and ordinary temperature in the course of molding the
fiber-reinforced resin, and a product manufactured by the manufacturing method. There is accordingly provided a manufacturing method of a coated
fiber-reinforced resin molded article and a product manufactured by the manufacturing method. The manufacturing method comprises a first molding process that cures a matrix resin which a reinforcing fiber is impregnated with at a temperature T1(° C.) to obtain a fiber-reinforced resin molded article; and a second molding process that places the fiber-reinforced resin molded article in a cavity of a mold, sets the cavity to a temperature T2(° C.) that is lower than the temperature T1(° C.), injects a liquid
coating layer-forming resin material into the cavity such as to coat at least part of a
surface layer of the fiber-reinforced resin molded article, and cures the
coating layer-forming resin material at the temperature T2(° C.), so as to obtain the coated fiber-reinforced resin molded article, wherein the mold is comprised of at least two pieces and has the cavity in a shape that is approximately same as a shape of the fiber-reinforced resin molded article.
