Resin composition excellent in stability to face impact

A resin composition containing (a) a polyamide;

• (b) a polyphenylene ether;
• (c) at least one partially hydrogenated block copolymer;
• (d) copper;
• and (e) titanium dioxide and/or carbon black, wherein
• the polyphenylene ether (b) in the composition has a weight average molecular weight in the range of 45,000-65,000,
• the partially hydrogenated block copolymer (c) is a partially hydrogenated product of an ABA type and/or an ABAB type block copolymer comprising an aromatic vinyl compound block (A) and a conjugated diene compound block (B),
• the copper (d) is contained in an amount of 1-20 mass ppm based on the total mass of the resin composition,
• the titanium dioxide and/or carbon black (e) are contained in an amount of 0.1-2 mass % based on the total mass of the resin composition,
• the polyamide (a) forms a continuous phase, the polyphenylene ether (b) is dispersed in the continuous phase to form a dispersed phase, the partially hydrogenated block copolymer (c) is present in at least one phase selected from the continuous phase of the polyamide (a) and the dispersed phase of the polyphenylene ether (b), whereby when the partially hydrogenated block copolymer (c) is present in the dispersed phase of the polyphenylene ether (b), the partially hydrogenated block copolymer (c) forms a dispersed phase together with the polyphenylene ether (b) and when the partially hydrogenated block copolymer (c) is present in the continuous phase of the polyamide (a), the partially hydrogenated block copolymer (c) singly forms a dispersed phase different from the dispersed phase of the polyphenylene ether (b), and
• the dispersed phase containing the polyphenylene ether (b) and/or the partially hydrogenated block copolymer (c) dispersed in the polyamide (a) has a ratio (Dv/Dn) of a volume average particle diameter (Dv) and a number average particle diameter (Dn) in the range of 2.0-5.0.
