A flame-retardant thermoplastic resin composition comprising at least a plant-derived resin (A) and a flame retardant (B), wherein the weight proportions of the individual components in the flame-retardant thermoplastic resin composition are: 30≰W1<55.5 44.5<X1≰70 wherein W1 is the percentage by mass of the plant-derived resin (A) and X1 is the percentage by mass of the flame retardant (B), and 90% by mass or more of the flame retardant (B) is composed of a metal hydrate containing an alkali metal-based substance in an amount of 0.2% by mass or less. |
