Abstract
(EN)
This thermoplastic resin composition is characterized by containing not less than 20 parts by mass but less than 50 parts by mass of a polyalkylene terephthalate resin (A), and more than 50 parts by mass and not more than 80 parts by mass of a polystyrene resin or a rubber-reinforced polystyrene resin (B) with respect to a total of 100 parts by mass of (A) and (B), wherein the polyalkylene terephthalate resin (A) has an inherent viscosity (IVA) of 0.3-0.8 dl/g, and the polystyrene resin or the rubber-reinforced polystyrene resin (B) has a melt viscosity (ηB) of 80 Pa·sec or more at 250°C and 912 sec-1.
