Patent ID: 8865804

Claim:
A resin composition, comprising components (A), (B), (C), and (D), wherein, based on a total content of components (A), (B), (C), and (D), a content (<A>) of the component (A), which is a polyphenylene ether, is 20% by weight or more but less than 21% by weight, a content (<B>) of the component (B), which is a hydrogenated copolymer principally comprising an aromatic vinyl monomer unit and a conjugated diene monomer unit, is 57% by weight or more but 59% by weight or less, a content (<C>) of the component (C), which is a styrene resin and/or olefin resin, is 0% by weight or more but 40% by weight or less, and a content (<D>) of the component (D), which is an aluminum phosphinate is 2% by weight or more but 15% by weight or less, and wherein the component (B) comprises (B1) a polymer block principally comprising an aromatic vinyl monomer unit, and (B2) a hydrogenated copolymer block principally comprising an aromatic vinyl monomer unit and a conjugated diene monomer unit; and a content of the aromatic vinyl monomer unit in the (B2) is 20% by weight or more and 95% by weight or less, and wherein the content of the aromatic vinyl monomer unit in the component (B) is 35% by weight or more and 80% by weight or less, and the ratio of the content (<B>) of the component (B) to the content (<A>) of the component (A) is from 2.71 to 2.95.
