Abstract
A flame-retardant resin composition including a resin component containing (A) 30 to 90 parts by weight of a thermoplastic polyurethane elastomer having, as measured according to JIS K 7311, a JIS hardness of A98 or less, (B) 70 to 10 parts by weight of an ethylene-vinyl acetate copolymer having a vinyl acetate unit content of 50 to 90% by weight, (C) 0 to 40 parts by weight of at least one polymer selected from the following copolymers (C1) to (C3), (C1) an acid anhydride-modified ethylene-unsaturated carboxylic acid derivative copolymer, (C2) an epoxy group-having ethylene-olefin copolymer, and (C3) an acid anhydride-modified styrene elastomer, and provided that the total amount of components (A), (B) and (C) is 100 parts by weight, (D) a metal hydroxide in a ratio of 40 to 250 parts by weight with respect to the total amount of 100 parts by weight of the resin component containing (A), (B) and (C).
