摘要： Provided is a double-sided pressure-sensitive adhesive tape, which is excellent in initial pressure-sensitive adhesive property to an adherend, is sufficiently elongated, hardly breaks even when sufficiently elongated, can be smoothly pulled and removed from the adherend under an elongated state, and is excellent in reworking properties. The double-sided pressure-sensitive adhesive tape in an embodiment of the present invention includes, in this order: a pressure-sensitive adhesive layer (B1); a base material layer (A); and a pressure-sensitive adhesive layer (B2), wherein the pressure-sensitive adhesive layer (B1) and the pressure-sensitive adhesive layer (B2) each contain at least one kind selected from the group consisting of: an acrylic pressure-sensitive adhesive; and a rubber-based pressure-sensitive adhesive, and the acrylic pressure-sensitive adhesive contains a filler, wherein the base material layer (A) contains, as a resin component, at least one kind selected from the group consisting of: polyolefin; thermoplastic polyurethane; and a styrene-based polymer.
