PROBLEM TO BE SOLVED: To provide a flame-retardant resin composition etc. 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, homo-polypropylene resin, and a flame-retardant agent. The ethylenic polymer percentage content in the total of 100 mass% of ethylenic polymer, the acid-modified thermoplastic resin and homo-polypropylene resin is 55 to 68 mass%, the acid-modified thermoplastic resin percentage content is 30 to 40 mass%, and homo-polypropylene resin percentage content is 2 to 5 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 homo-polypropylene resin. 【課題】優れた難燃性及び優れた機械的特性を確保しながら、優れた耐加熱変形特性をも確保することができる難燃性樹脂組成物などを提供すること。【解決手段】 エチレン系重合体と酸変性熱可塑性樹脂とホモポリプロピレン樹脂と難燃剤とを含み、エチレン系重合体と前記酸変性熱可塑性樹脂とホモポリプロピレン樹脂との合計１００質量％中のエチレン系重合体の含有率が５５~６８質量％、酸変性熱可塑性樹脂の含有率が３０~４０質量％、ホモポリプロピレン樹脂の含有率が２~５質量％であり、エチレン系重合体と酸変性熱可塑性樹脂とホモポリプロピレン樹脂との合計１００質量部に対して難燃剤が８０〜９６質量部の割合で配合されている難燃性樹脂組成物。【選択図】なし
