PROBLEM TO BE SOLVED: To obtain an adhesive sheet which has excellent adhesivity, is peelable when used in piling up a plurality of sheets and can be incinerated by simple facilities. SOLUTION: This adhesive sheet is obtained by laminating an adhesive layer to a polyolefin substrate layer. When a plurality of adhesive sheets A and B are piled in the order of A (substrate layer-adhesive layer) -B (substrate layer-adhesive layer) and used, the piled adhesive sheets A and B are peelable. Preferably the adhesive strength between the adhesive layer of the adhesive sheet and the substrate layer of the adhesive sheet B is 3.0-6.0 N/25 mm, more preferably the adhesive strength of the adhesive layer is 10-13 N/25 mm adhesive strength of stainless steel plate described in JIS Z0237 and more preferably the adhesive used in the adhesive layer is an acrylic resin adhesive.
