PURPOSE: To provide a resin composition comprising crystalline polypropylene resin, polyethylene resin and a hydrogenated styrene-conjugated diene block copolymer rubber, good in moldability, and giving molding therefrom good in appearance and physical properties.

CONSTITUTION: The objective resin composition comprises (A) crystalline polypropylene resin, (B) polyethylene resin, and (C) a hydrogenated styrene/ conjugated diene random block copolymer rubber having a styrene content of 3-20wt.%, a styrenic block part content of ≤10wt.% and a vinylic bond content of >60wt.% in the conjugated diene parts at a (B+C)/A ratio of 5-70/95-30 and a B/C of 10-50/90-50. The resin composition is good in moldability and excellent in flexibility, and gives molding therefrom excellent in impact resistance, whitening resistance, product appearance such as surface luster and the balance of physical properties, and contains dispersed particles consisting mainly of the component B and having an average dispersed particle diameter of ≤0.5μ.
