PROBLEM TO BE SOLVED: To supply a laminated sheet which shows a stable peeling strength, i.e., a wide range of temperatures at which thermocompression bonding is possible, even if the temperatures for thermocompression bonding slightly fluctuates, in the manufacture of the laminated sheet which can be thermocompression bonded and repeeled. SOLUTION: This thermocompression bondable and repeelable laminated sheet consists of a base material layer, a biaxially stretched polypropylene film layer and a thermocompression bondable resin layer stacked in that order, and the thermocompression bondable resin layer comprises a copolymer of propylene andαolefine and crystalline polybutene. The copolymer of propylene andαolefin is preferably a copolymer of ethylene and propylene or a copolymer of ethylene, propylene and butene.
