Zusammenfassung:	To provide a pressure sensitive adhesive sheet excellent in designability while securing a conduction path for air bubble removal.SOLUTION: A pressure sensitive adhesive sheet 1 includes: an extensible film layer 10; an adhesive layer 15 formed on one face side of the extensible film layer; a releasable sheet 18 formed on the opposite face side of the extensible film layer of the adhesive layer; and a groove part 16 formed on the opposite face side of the extensible film layer of the adhesive layer. The groove part may be terminated at an outer peripheral part of the adhesive layer, or may be communicating with another groove part that is terminated at an outer peripheral portion of the adhesive layer.SELECTED DRAWING: Figure 1 【課題】気泡除去の導通路を確保しつつ、意匠性にも優れた粘着シートを提供する。【解決手段】伸展性フィルム層１０と、前記伸展性フィルム層の一方の面側に形成された粘着剤層１５と、前記粘着剤層の前記伸展性フィルム層と反対の面側に形成された剥離性シート１８と、を備え、前記粘着剤層の前記伸展性フィルム層と反対の面側に形成された溝部１６を有し、前記溝部が前記粘着剤層の外周部分で終端すること、もしくは前記粘着剤層の外周部分で終端する他の溝部と連通することを特徴とする粘着シート１。【選択図】図１
