A flame-retardant thermoplastic resin composition, comprising a thermoplastic resin (a) and an inorganic flame-retarder (b), the content of the component (b) being 50 to 250 parts by mass with respect to 100 parts by mass of the component (a), wherein the component (a) includes at least one selected from the group consisting of an alpha-olefin (co)polymer (a-1), a thermoplastic elastomer (a-2) and a rubber (a-3); the component (a) (100% by mass) includes 0.01 to 0.5% by mass of a constituent unit derived from an unsaturated monomer having a carboxylic acid group or acid anhydride group; the component (b) includes 40 to 95% by mass of inorganic metal hydrate (b-1) and 5 to 60% by mass of inorganic filler (b-2); and the average particle diameter of the inorganic filler (b-2) is not more than 2 mum and the aspect ratio of the inorganic filler (b-2) is not more than 1.5.
