PROBLEM TO BE SOLVED: To provide a method for efficiently manufacturing a styrenic resin laminate enhanced in toughness while holding various properties of an SPS/ GPPS laminate. SOLUTION: The styrenic resin laminate is manufactured by co-extruding a styrenic polymer with a mol. weight of 150,000-350,000 having a syndiotactic structure or a composition (A) containing this polymer and a styrenic polymer with a mol.wt. of 220,000 or more having an atactic structure, or a composition (B) containing this polymer, in a molten state at 250-300 deg.C. The co-extrudate is heat treated at 160 deg.C or less to manufacture the styrene resin laminate.
