Abstract: Provided is a PSA tape for an electrochemical device, which can be peeled off rapidly and will not damage adherend materials or the PSA tape itself, or will not leave adhesive residues, when an adhesion defectiveness occurs during the manufacturing and processing of an electrochemical device, especially an electrolytic capacitor or a battery. The PSA tape comprises a substrate and a PSA layer placed on at least one face of the substrate. In the PSA tape, an anchoring strength of the PSA layer to the substrate is 7.0 N/10 mm or more.

Abstract: Disclosed is a pressure-sensitive adhesive tape or sheet which does not cause deterioration of an electrolytic solution even when immersed in the electrolytic solution and which can be smoothly unwound even after being wound. The pressure-sensitive adhesive tape or sheet includes a substrate and, on one surface thereof, a pressure-sensitive adhesive layer. The substrate has a wetting tension of from 30 to 35 mN/m in the surface to face the pressure-sensitive adhesive layer, where the wetting tension is measured by a method according to JIS K 6768:1999. The pressure-sensitive adhesive layer includes a pressure-sensitive adhesive containing substantially no polar group. A pressure-sensitive adhesive in the pressure-sensitive adhesive layer is preferably a rubber pressure-sensitive adhesive such as a polyisobutylene rubber and/or an isobutylene-isoprene rubber.
