PROBLEM TO BE SOLVED: To provide a molded product composed of a composite material of plant fibers and a synthetic resin, hardly causing color shift over many years, and to provide its production method. SOLUTION: The production method for the molded product is characterized by molding a composite material containing: waste paper pulp, prepared by disintegrating waste paper; a block polypropylene; an olefinic rubber (an ethylene-butene copolymer); a basic compound of magnesium hydroxide or calcium stearate; and a hindered amine light stabilizer, by using an injection molding machine or the like after melt-kneading the composite material.
