PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive fastener reducing positional deviation of an article, applying little damage to an object when peeling, reducing residues of the pressure-sensitive adhesive on the object after the peeling, and capable of facilitating re-sticking thereof.SOLUTION: A pressure-sensitive adhesive fastener 100 is connected to an object 150 by superposing one surface 110a side including a pressure-sensitive adhesive layer 121 and a projection member 130 to the object 150. In a state where the pressure-sensitive adhesive fastener 100 and the object 150 are connected, besides the pressure-sensitive adhesive layer 121 is joined with the object 150, a part of a column part 131 and an insertion part 132 of the projection member 130 enter a gap of the object 150. Accordingly, the projection member 130 is stuck into the object 150 so as to suppress the positional deviation between the pressure-sensitive adhesive fastener 100 and the object 150.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,JPO&INPIT【課題】物品の位置ずれを低減し、剥離時における対象物へのダメージが小さく、剥離後の対象物への感圧接着剤の残留を低減し、且つ、貼りなおしが容易に可能な感圧接着ファスナーを提供する。【解決手段】感圧接着ファスナー100は、感圧接着剤層121及び突出部材130を備えた一方の面110a側を対象物150と重ね合わせることにより、対象物150と連結される。感圧接着ファスナー100と対象物150とが連結された状態では、感圧接着剤層121が対象物150と接合されることに加え、突出部材130の柱部131の一部及び挿入部132が対象物150の隙間に入り込む。これにより、突出部材130が対象物150に突き刺さるような態様となることで、感圧接着ファスナー100と対象物150との位置ずれを抑制することができる。【選択図】図4
