Abstract

To provide a biaxially oriented sheet with excellent oil resistance and toughness. [Solution] A styrene-based biaxially oriented sheet comprising a copolymer (A) containing vinyl cyanide monomer units and styrene monomer units, a copolymer (B) containing maleimide monomer units and styrene monomer units, and a copolymer (C) containing butadiene units and styrene monomer units, wherein the content of butadiene units is 0.2% by mass or more and 2.5% by mass or less based on the total mass of the styrene-based biaxially oriented sheet.
