PROBLEM TO BE SOLVED: To provide a polystyrene resin sheet which is excellent in fogging- proof at a high and low temperature and mold-releasability or peelability of the sheet and has a low electrification property when molded, and is suitably used for secondary processing. SOLUTION: In this polystyrene resin sheet, at least one kind of surfactants selected as a fogging-proof agent from a sucrose fatty acid ester and a polyglycerol fatty acid ester is coated on an one surface in an amount of 5-30 mg/m2, and a polyether compound is coated on the opposite surface in an amount of 3-20 mg/m2 as the mold-releasing agent. |
