PROBLEM TO BE SOLVED: To provide a producing method of a propylene resin composition which is excellent in rigidity, impact resistance, and particularly appearance of a molded product while transparency is maintained, and to provide an injection-molded product made from the propylene resin composition. SOLUTION: The producing method of the propylene resin composition comprises adding (D) 0.0001-0.03 pt.wt. of an organic peroxide, to 100 pts.wt. of a mixture of (A) 45-96 pts.wt. of a propylene-ethylene randam copolymer having a melt flow rate (hereafter referred to as MFR) of 0.5-50 g/10 min and an ethylene content of 2.0-5.0 wt.%, (B) 2-15 pts.wt. of an ethylene-α-olefin copolymer having an MFR of 5-70 g/10 min and a density of 0.860-0.913 g/cm<SP>3</SP>, and being made by a metallocene catalyst, (C) 2-40 pts.wt. of a propylene single polymer having an MFR of 0.5-30 g/10 min, a ratio of the (D)/the (B) being≤1/100, making a serial melt kneading or a segmentation melt kneading, and obtaining the resin composition having an MFR being by 1.2-3 times that of the (A).
