1. A resin composition comprising (a) a polypropylene-based resin, (b) a polyphenylene ether-based resin, and (c) a first hydrogenated block copolymer-based resin, and further comprising (d) an ethylene-α-olefin copolymer rubber and/or (e) a second hydrogenated block copolymer-based resin, wherein
each of the components (c) and (e) is a hydrogenated block copolymer prepared by hydrogenating a block copolymer comprising at least one polymer block A composed mainly of a vinyl aromatic compound and at least one polymer block B composed mainly of a conjugated diene compound, and/or a modified product of the hydrogenated block copolymer, a total ratio of a 1,2-vinyl bond and a 3,4-vinyl bond to all bonds in the conjugated diene compound units in the component (c) is 45 to 90%, the component (c) comprises 30 to 50% by mass of the vinyl aromatic compound units, a total ratio of a 1,2-vinyl bond and a 3,4-vinyl bond to all bonds in the conjugated diene compound units in the component (e) is 25% or more and less than 60%, a rate of hydrogenation of ethylenic double bonds (double bonds in the conjugated diene compound units) in the block copolymer in the component (c) is 80 to 100%, and a rate of hydrogenation of ethylenic double bonds (double bonds in the conjugated diene compound units) in the block copolymer in the component (e) is 10% or higher and lower than 80%. |
