Abstract
A styrene resin composition includes: a resin (A) comprising a styrene resin (A1) having a syndiotactic structure and an aliphatic polyamide (A2); and 0.05 to 0.75% by mass of a metal salt (B) of a higher fatty acid. The mass ratio [(A1)/(A2)] between the styrene resin (A1) and the aliphatic polyamide (A2) in the resin (A) is 25/75 to 55/45.

A styrene resin composition comprising:
- a resin (A) comprising a styrene resin (A1) having a syndiotactic structure and an aliphatic polyamide (A2);
- 0.07 to 0.2% by mass of aluminum stearate;
- and a compatibilizer (C) which is compatible with the styrene resin (A1), and has a polar group reactive with the aliphatic polyamide (A2), wherein the compatibilizer (C) is a modified polyphenylene ether, wherein the mass ratio [(A1)/(A2)] between the styrene resin (A1) and the aliphatic polyamide (A2) in the resin (A) is 25/75 to 50/50.
