PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition having a high heat conductivity, a high electric insulation, and excellent in flame retardancy and light resistance and injection moldability. SOLUTION: The thermoplastic resin composition contains at least a thermoplastic polyesteric resin (A), a boron nitride powder (B), and an organophosphinate salt-based flame retardant (C), wherein the volume ratio (A)/(B) is 85/15 to 25/75, and (C) is 0.5 to 20 wt.% to the total amount of the resin composition. The thermoplastic resin composition has a color difference ΔE of ≤10 between before and after an irradiation when the composition is irradiated continuously for 7 days from a distance of 10 cm by a 400 W mercury lamp in a 120°C atmosphere, and has a heat conductivity of ≥2 W/m×K, a surface electric resistance value of ≥10<SP>11</SP>Ω, and a low density. Thermoplastic resin molded articles very useful for weight reduction and thermal countermeasures for illuminating fixing members and mobile electric devices are easily molded form the thermoplastic resin composition.
