ABSTRACT:
Injection molding is carried out by using styrene-based resin composition. As to the styrene-based resin composition, styrene-based resin, in which melt flow index is 3.0-40.0 g/10 minutes, a Rockwell hardness is M38 or more, an Izod impact strength is 2.0 Kg.multidot.cm/cm or more, a bending elastic modulus is 20,000 Kg/cm.sup.2 or more, and a Vicat softening point is 78.degree. C. or more, is 50 wt. % or more, total of at least two kinds selected from lubricant or surfactant is 0.01-20 wt. %, a thermoplastic resin having experienced twice or more heat histories at 150.degree. C. or more is 3 wt. % or more, and total of at least one of antioxidant, deodorant and an agent imparting fragrance is 0.01-20 wt. %. Styrene-based resin composition having melt flow index of 1-50 g/10 minutes, and including ethylbenzene of 0.001-1 wt. %, rubber-like material of 0.1-15 wt. %, and light shielding material of 0.1-10 wt. %, may be used.
