PROBLEM TO BE SOLVED: To provide an adhesive sheet capable of sufficiently suppressing transfer of winding marks onto an adhesive layer, also sufficiently suppressing the generation of voids due to entraining of air by winding when pasting the adhesive layer onto an adherend, in the case of winding the adhesive sheet, which has an adhesive layer formed in a prescribed planar form by pre-cut processing or the like, in rolled state. SOLUTION: The adhesive sheet is formed by islanding a plurality of sets, each of which is formed by laminating an adhesive, a pressure-sensitive adhesive covering the adhesive, being fairly larger than the adhesive and having a fringe part not overlapping the adhesive, and a protective film overlapping the pressure-sensitive adhesive for protecting it, in this order, on one surface of a long base material; and adhesive sheet is wound in rolled state and a core material for winding the adhesive sheet has buffering property.
