[Problem] To provide a pressure-sensitive adhesive tape or sheet which has fewer limitations during adhesion by virtue of maintaining, over an arbitrary period of time after being brought into contact with the adherend, the function of facilitating removal of fluids such as gases or liquids that enter into gaps between the adherend and the pressure-sensitive adhesive tape or sheet during adhesion. [Solution] This pressure-sensitive adhesive tape or sheet is characterized by comprising at least a support layer and a pressure-sensitive adhesive layer and by having grooves, wherein the maximum depth of said grooves from the surface contacting the adherend surface of the pressure-sensitive adhesive layer is 50-100% of the thickness of the pressure-sensitive adhesive layer and is 45-50µm, and the maximum width is 10-100% of the thickness of the pressure-sensitive adhesive layer. |
