Abstract:
1. A resin composition comprising (A) polyphenylene ether, (B) a hydrogenated block copolymer which is obtained by hydrogenating a block copolymer including a polystyrene block and a conjugated diene compound polymer block, and which has a weight average molecular weight of 100,000 to 500,000, and (C) an organic phosphorus-based flame retardant, wherein the resin composition comprises, based on 100 parts by mass of a total amount of the (A) component, the (B) component and the (C) component, 57 to 94 parts by mass of the (A) component, 3 to 30 parts by mass of the (B) component, and 3 to 30 parts by mass of the (C) component; and wherein a value of a loss tangent (tan δ) peak height of the (B) component, represented by the following equation 1, in a dynamic viscoelasticity spectrum obtained by measurement of the resin composition at a frequency of 10 Hz is in a range of 0.075 to 0.120;
