PROBLEM TO BE SOLVED: To provide a biaxially stretched styrene resin laminated sheet which has excellent transparency, and in which deep draw forming can be performed without generating a rain-drop at a forming time. SOLUTION: The biaxially stretched styrene resin laminated sheet comprises surface layers (A) containing a styrene copolymer (a1) obtained by copolymerizing a styrene monomer and an ethylenic unsaturated carboxylic acid as indispensable components as both surface layers and a hydrogenated petroleum resin (a2) as both surface layers, and an intermediate layer (B) containing a styrene resin (b1) as the intermediate layer interposed between both the surface layers.
