PROBLEM TO BE SOLVED: To provide a heat-resistant polystyrene resin expanded laminated sheet having high heat resistance and excellent economy, wherein brittleness, moldability, appearance or the like is improved considerably, and provide a mold such as a food container or the like using it. SOLUTION: The heat-resistant polystyrene resin expanded laminated sheet having a laminated structure comprises a heat-resistant polystyrene resin expanded layer having a density of 0.5-0.05 g/cm3, and a polystyrene resin expanded layer having a density of 0.5-0.05 g/cm3. An entire density is 0.35-0.05 g/cm3, and a total thickness is 0.5-3 mm. The mold is manufactured by thermoforming so that the heat-resistant polystyrene resin expanded layer is arranged on an inner face side.
