Abstract: Provided is a conductive pressure-sensitive adhesive tape that achieves both strong adhesion to an adherend and a reworking property. A conductive pressure-sensitive adhesive tape (1) includes a pressure-sensitive adhesive layer (2) containing a pressure-sensitive adhesive resin containing a pressure-sensitive adhesive polymer and conductive particles (4) dispersed in the pressure-sensitive adhesive resin, in which: the pressure-sensitive adhesive layer (2) has a surface layer (22) that is formed of the pressure-sensitive adhesive resin and that forms a surface of the pressure-sensitive adhesive layer; and a thickness of the surface layer (22) includes an analysis depth from the surface of the pressure-sensitive adhesive layer when a spectral intensity derived from the conductive particles in glow discharge spectrometry becomes one half of a maximum thereof, and is 0.1 μm or more and 0.9 μm or less.

Abstract: Provided is a filler-containing pressure-sensitive adhesive tape having an excellent pressure-sensitive adhesive strength while suppressing the occurrence of a volatile component. The filler-containing pressure-sensitive adhesive tape includes a pressure-sensitive adhesive layer containing a pressure-sensitive adhesive resin containing an acrylic polymer and a filler dispersed in the pressure-sensitive adhesive resin, in which the acrylic polymer contains at least a constituent unit derived from a (meth)acrylic acid alkyl ester having a linear or branched alkyl group having 1 to 20 carbon atoms, a constituent unit derived from a nitrogen-containing monomer, and a constituent unit derived from a carboxyl group-containing monomer, and has a ratio (mass ratio) of the constituent unit derived from the carboxyl group-containing monomer to the constituent unit derived from the nitrogen-containing monomer of from 0.01 to 40.

Abstract: Provided is a pressure-sensitive adhesive (PSA) sheet including a PSA layer formed from a PSA composition including a base polymer, crosslinking agents of two or more species having mutually different types of crosslinkable functional groups, and an azole-based rust inhibitor. Here, one of the crosslinking agents of two or more species is an isocyanate-based crosslinking agent. Monomeric components constituting the base polymer include a carboxy group-containing monomer. The amount of the azole-based rust inhibitor in the PSA layer is less than 8 parts by weight with respect to 100 parts by weight of the base polymer.
