Zusammenfassung:	To provide a polystyrene-based resin sheet that has a good oil resistance even under a high-temperature condition, and that hardly causes a gel-state foreign matter when mill ends in a manufacturing process are reused (recycled) as a raw material.SOLUTION: There is provided a polystyrene-based resin sheet that comprises: a base sheet containing a polystyrene-based resin as a main component; and a coating layer provided on at least one of surfaces of the base sheet. The coating layer contains a polyvinyl alcohol-based resin (A) having a primary hydroxyl group in a side chain as a main component.SELECTED DRAWING: None 【課題】高温条件下においても良好な耐油性を備え、更に製造工程の端材を原材料として再利用（リサイクル）する際にゲル異物の発生し難いポリスチレン系樹脂シートを提供する。【解決手段】ポリスチレン系樹脂を主成分としてなる基材シート、および、該基材シートの少なくとも一方の面に被覆層を有するポリスチレン系樹脂シートであって、前記被覆層は、側鎖に一級水酸基を有するポリビニルアルコール系樹脂（Ａ）を主成分として含む、ポリスチレン系樹脂シート。【選択図】なし
