(57) [Problem] To provide a PBT resin composition having flame retardancy and high tracking resistance. A resin composition comprising (A) polybutylene terephthalate and (B) a polyester elastomer, further comprising (C) a brominated flame retardant 4 to 12 % By weight, (D) 2 to 6% by weight of an antimony-based flame retardant aid (E) 3 to 10% by weight of a fluorinated ethylene polymer, (F) 3 to 10% by weight of a polyolefin, (G) a metal silicate-based filler, and (H) a glass fiber, and The content ratio of (A) and (B) is (A) / (B) = 95 / 5 to 60/40, the content ratio of (G) and (H) is (G) / (H) = 15/85 to 65/35, and the total amount of (G) and (H) is 30 to 40% by weight. |
