PROBLEM TO BE SOLVED: To provide a flame-retardant thermoplastic resin composition which is free from the deterioration of physical properties even when a large amount of an inorganic flame retardant is incorporated, is excellent in heat resistance and low temperature resistance and also is excellent in the processability for insulation displacement contact. SOLUTION: The flame-retardant thermoplastic resin composition is prepared by melting/kneading (A) 100 pts.mass of a thermoplastic resin component, (B) 120-300 pts.mass of an inorganic flame retardant, (C) 0.001-2 pts.mass of an organic peroxide, (D) 0-4 pts.mass of a (meth)acrylate-based and/or allyl-based crosslinking aid and (E) 0-2 mass% of a silane coupling agent based on the amount of the component (B), at a temperature of the 1-minute half-life temperature of the organic peroxide (C) or higher. The above thermoplastic resin component (A) comprises (a) 10-80 mass% of a propylene-based elastomer and/or propylene-based plastomer, (b) 10-80 mass% of a crystalline propylene-based resin and (c) 5-25 mass% of other components.
