PROBLEM TO BE SOLVED: To provide an adhesive sheet worked by pre-cut processing and capable of enough controlling insufficiency of release of an adhesive layer, a pressure-sensitive adhesive layer, and a base film from a release base. SOLUTION: This adhesive sheet has such a structure that the release base, the adhesive layer, the pressure-sensitive adhesive layer, and the base film are sequentially laminated, wherein the adhesive layer has a prescribed first planar shape and is partially formed on the release base, the release base has a first notched part which is formed along the periphery of the first planar shape from a surface on a side attaching to the adhesive layer, and a notched depth of the first notched part is less than a thickness of the release base and not more than 25μm.
