PROBLEM TO BE SOLVED: To provide an adhesive sheet which allows efficient pulling removal while preventing or suppressing damage, like being torn off.SOLUTION: An extensible adhesive sheet comprises an adhesive layer and a film-like substrate for supporting the adhesive layer. The adhesive sheet has a long-sized part, and the long-sized part has a taper part which extends in a tapered form toward one end in the longitudinal direction. The minimum cross-section of the film-like substrate in the taper part is greater than 0.30 mm.SELECTED DRAWING: Figure 2 【課題】千切れ等の損傷を防止または抑制しつつ、効率よく引張り除去することが可能な粘着シートを提供する。【解決手段】粘着剤層と、該粘着剤層を支持するフィルム状基材と、を備える伸長性粘着シートが提供される。前記粘着シートは長尺部を有している。また、前記長尺部は、長手方向の一端に向かってテーパ状に延びるテーパ部を有し、かつ前記テーパ部における前記フィルム状基材の最小断面積は０．３０ｍｍ２より大きい。【選択図】図２
