PROBLEM TO BE SOLVED: To provide a heat-resistant polystyrene resin foaming laminated sheet and its molded product by which the occurrence of blisters is reduced by strongly adhering the heat-resistant polystyrene resin foaming laminated sheet and a polypropylene resin film. SOLUTION: The heat-resistant polystyrene resin foaming laminated sheet is constituted by laminating a heat-resistant foaming sheet comprising a heat-resistant polystyrene resin having a Vicat softening point specified by JIS K7206 of 110°C or more and the polypropylene resin film via a adhesive ink layer by heat fusion bonding, and the adhesive ink layer is constituted of at least two layers, an adhesive ink layer whose base material is a chlorinated polypropylene resin is arranged in the side of the polypropylene resin film, and an adhesive ink layer whose base material an acrylic resin is arranged in the side of the heat-resistant foaming sheet.
