Acid-modified acid to which unsaturated carboxylic acid or its derivative is added to the hydrogenated block copolymer of the weight average molecular weight 50,000-500,000 which consists of the polymer block A mainly a vinyl aromatic compound unit, and the polymer block B mainly a conjugated diene unit. As the hydrogenated block copolymer, a powdery acid-modified hydrogenated block copolymer (a) having a bulk density of 0.1 to 0.4 g / ml, a polyolefin resin (b), a softener for vinyl aromatic rubber (c), and a metal hydrate ( The flame retardant composition which consists of d) and contains these in the ratio which satisfy | fills following formula (1)-(3).n n n 0.1≤Wa / (Wa + Wb) ≤0.9 (1)n n n 0.05≤Wc / (Wa + Wb + Wc) ≤0.5 (2)n n n 0.4≤Wd / (Wa + Wb + Wc + Wd) ≤0.75 (3)n n n [Wherein, Wa, Wb, Wc and Wd represent the mass of the acid-modified hydrogenated block copolymer (a), the polyolefin resin (b), the softener for the non-aromatic rubber (c) and the metal hydrate (d), respectively. do]. |
