PROBLEM TO BE SOLVED: To provide a polypropylene resin composition which is excellent in balance among physical properties, weld appearance and flow mark appearance and has high profitability and to provide a molding of the polypropylene resin composition. SOLUTION: The polypropylene resin composition includes component (I) of 5-94 wt.% propylene block copolymer which is polymerized by using a metallocene catalyst and satisfies specified conditions, component (II) of 5-70 wt.% propylene polymer which is polymerized by using the metallocene catalyst and satisfies specified conditions, component (III) of 1-60 wt.% inorganic filler and, if necessary, component (IV) of an elastomer of 1-20 pts.wt. (on the basis of 100 pts.wt. total amount of components (I) to (III)). COPYRIGHT: (C)2009,JPO&INPIT
