Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fiber-reinforced polypropylene-based resin composition with low shrinkage and satisfactory grain transferability, scratch resistance and molding appearance, smooth and soft touch feeling of molding surface without foaming, and further high in rigidity, impact resistance and heat resistance; production method and molding thereof.SOLUTION: This fiber-reinforced polypropylene-based resin composition includes a propylene-ethylene block copolymer satisfying four requirements such as sequential polymerization using a metallocene-based catalyst, a specific fiber and, as needed, a specific modified polyolefin, a thermoplastic elastomer satisfying two requirements such as MFR, a specific propylenic polymer resin and a specific aliphatic amide and the like.
