Provided are: a flame-retardant polybutylene terephthalate resin composition which exhibits excellent flame retardancy, glow-wire properties (GWIT), tracking resistance and bleed resistance in spite of a fact that a polybutylene terephthalate resin is used as a sole resin component; and a molded product of the resin composition. A flame-retardant resin composition comprising (A) a polybutylene terephthalate resin, (B) a phosphinic acid salt, (C) a phosphazene compound and (D) a nitrogenated cyclic compound, said resin composition being characterized in that the level of the flame retardancy as measured in accordance with a UL94 combustion test is V-0, the glow-wire ignition temperature (GWIT) as measured in accordance with IEC60695-2-13 standard is 775˚C or higher, the comparative tracking index (CTI) as measured in accordance with IEC60112 standard is 400 V or more, and bleed out does not occur when the resin composition is treated at 110˚C for 20 hours. |
