PROBLEM TO BE SOLVED: To provide a resin composition rich in resistances to heat and oil and excellent in tensile elongation properties by adding a partially hydrogenated block copolymer to a blend of a styrene resin and an olefin resin. SOLUTION: This resin composition contains (A) 95-5 pts.wt. styrene resin, 5-95 pts.wt. olefin resin, and, based on 100 pts.wt. sum of resins A and B, (C) 2-30 pts.wt. hydrogenated block copolymer which has a degree of hydrogenation of 35% or higher but lower than 70% and is obtained by partially hydrogenating a block copolymer containing at least one polymer block formed mainly from an aromatic vinylhydrocarbon and at least one polymer block formed mainly from a conjugated diene compound and having a content of units derived from the aromatic hydrocarbon of 30-80 wt.% and a vinyl bond content in the conjugated diene block of 20-90 wt.%.
