PROBLEM TO BE SOLVED: To provide a resin composition excellent in warpage, molding cycle, stiffness, heat resistance and steam permeation resistance simultaneously. SOLUTION: This resin composition is provided by consisting of 5 to 30 pts.wt. hydrogenated block copolymer obtained by hydrogenating a block copolymer consisting of at least one polymer block A consisting mainly of (a) 45 to 95 pts.wt. polypropylene-based resin forming a matrix phase, (b) 55 to 5 pts.wt. polyphenylene ether-based resin forming a dispersed phase and (c) a vinyl aromatic compound based on 100 pts.wt. total of the components (a) and (b), and at least one polymer block B consisting mainly of a conjugated diene compound having 45 to 90% total amount of 1,2-vinyl bonds and 3,4-vinyl bonds of the conjugated diene compound, further consisting of (d) a fibrous inorganic filler having a 3 to 20μm mean diameter and (e) a plate like inorganic filler having 10 to 700μm mean flake diameter, and having 50 to 140 pts.wt. total of the components (d) and (e), and (70/30) to (30/70) weight ratio of them.
