Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a glittering polypropylene-based resin molded product having sufficiently high-grade metallic feeling and transparent feeling even though multiple coating film layer is not provided by metallic coating treatment or the like, and also capable of providing automotive parts excellent in appearance with no outstanding weld lines, flow marks and the like, and to provide a method for producing the molded product. SOLUTION: This glittering material-containing polypropylene-based resin molded product is obtained by directly forming a clear coating film layer on the surface of a molded basal form containing a glittering material comprising metal flakes, pearl mica, interference mica, metal-coated glass flakes or the like, and made from a polypropylene-based resin composition wherein the metallic degree is >=1.2 (a blend of a crystalline polypropylene with a propylene/ ethylene block copolymer).
