PROBLEM TO BE SOLVED: To provide a polystyrenic laminated foamed sheet, which is well-balanced between flexibility and strength, and used for molding a vegetable and fruit tray or the like. SOLUTION: The polystyrenic laminated foamed sheet is constituted by laminating a thermoplastic resin film with a thickness of 10-70μm on a foamed sheet comprising a mixed resin composed of a polystyrenic resin, a rubber modified polystyrenic resin and a styrenic elastomer resin. The breaking strength in the extrusion direction of the laminated foamed sheet is 2.5 kg/10 mm or above and the number of air bubbles in the thickness direction thereof is 10-18.
