PROBLEM TO BE SOLVED: To provide a polystyrene based resin laminated foamed sheet, the peel strength of whose film layer is improved in comparison with that of a conventional polystyrene based resin laminated foamed sheet and which is suitable as a slip sheet of a flat panel display or a glass substrate.SOLUTION: A polystyrene based resin laminated foamed sheet includes: a film layer which comprises a polystyrene based resin composition containing a polymer type antistatic agent and is disposed on at least one surface of the laminate foamed sheet; and a foamed layer which is disposed on the inside of the film layer and comprises a polystyrene resin composition. The foamed layer and the film layer are thermally bonded and layered on each other, and the polymer type antistatic agent contained in the film layer is an ionomer-based polymer antistatic agent. |
