When the total heat absorption measured by raising the temperature at a heating rate of 20 ° C./min by differential scanning calorific value measurement is 100%, the ratio of heat absorption obtained in the range of 175 to 260 ° C is less than 30%. It is composed of a styrene resin having a syndiotactic structure, 50 to 95% by mass of a thermoplastic resin composition, and 5 to 50% by mass of a glass filler, wherein the thermoplastic resin composition is Shinji. A phenol-based antioxidant and a sulfur-based antioxidant based on 100 parts by mass of a thermoplastic resin (SC A ) composed of 80 to 100% by mass of a styrene resin having an otakutic structure and 0 to 20% by mass of a rubber-like elastic body. 0.2 to 2.0 parts by mass of at least one antioxidant (SC B ) selected from the group consisting of, and at least one compound (SC C ) selected from the group consisting of polyphenylene ether and modified polyphenylene ether. ) A styrene resin composition containing 1.5 to 5.0 parts by mass and at least one selected from the group consisting of a nucleating agent and a mold release agent. |
