PROBLEM TO BE SOLVED: To provide a crystalline polypropylene resin composition suppressing a silver streak, burning and the like and obtaining a molded product having excellent surface appearance, to provide the molded product formed by injection-molding the resin composition and to provide a toilet seat, a toilet seat cover, or a housing or a case related thereto including the molded product. SOLUTION: The resin composition contains 1 to 25 pts.wt. following component (B), 3 to 50 pts.wt. organic flame retardant and 1 to 40 pts.wt. antimony compound to 100 pts.wt. following component (A). Component (A): a crystalline polypropylene having 10 to 200 g/10 min MFR, a Q value of 2 to 8 and≥95% isotactic triad fraction (mm). Component (B): a propylene-based polymer having 0.01 to 100 g/10 min MFR, a Q value of 3.5 to 10.5, 0.4 to 10 wt.% component ratio whose molecular weight of 2,000,000 or more in a molecular weight distribution curve,≤3.0 wt.% component eluted at≤40°C in TREF (temperature rising elution fractionation),≥95% isotactic triad fraction (mm) and a degree of strain hardening in measurement of elongational viscosity of 0.6 or more.
