PROBLEM TO BE SOLVED: To provide a flame-retardant resin composition that can ensure even an excellent heat-deformation resistant characteristic while ensuring an excellent flame-retardancy and mechanical property.SOLUTION: A flame-retardant resin composition comprises ethylenic polymer, acid-modified thermoplastic resin such as maleic anhydride-modified thermoplastic resin, polypropylene block copolymer having density of 0.90 g/cmor more, and a flame-retardant agent. The ethylenic polymer in the total of 100 mass% of ethylenic polymer, acid-modified thermoplastic resin and polypropylene block copolymer is 30 to 50 mass%, the acid-modified thermoplastic resin is 30 to 40 mass%, and polypropylene block copolymer is 20 to 40 mass%, and the flame-retardant agent is compounded in a ratio of 80 to 96 pts.mass per total of 100 pts.mass of ethylenic polymer, acid-modified thermoplastic resin and polypropylene block copolymer. |
