PROBLEM TO BE SOLVED: To obtain a resin composition excellent in any of tensile elongation, rigidity and residence heat stability.SOLUTION: A resin composition contains: (a) a polypropylene resin: 75 to 97 mass%; (b) a polyphenylene ether resin having reduced viscosity (chloroform solution of &eegr;sp/c: 0.5 g/dL, 30°C measurement) of 0.25-0.36 dL/g: 1-15 mass%; and (c) a hydrogenated block copolymer which is a hydrogen additive of a block copolymer containing at least two polymer blocks A containing a vinyl aromatic compound as a main component and at least one polymer block B containing a conjugated diene compound as a main component: 2-19 mass%. A number average molecular weight (MncA) of the polymer block A is less than 4,000-8,000, and a mass ratio ((b)/(c)) between the (b) component and the (c) component is 10/90 to 60/40. |
