Abstract: Provided is a PSA sheet having a PSA layer. The PSA layer includes a layer A forming at least one surface thereof. The PSA sheet has an adhesive strength N0 of 2.0 N/10 mm or greater, after one day at room temperature following application of the layer A side to a surface of an alkaline float glass plate as an adherend having a contact angle of 5°-10° with distilled water; has an N1 to N0 reduction rate of 30% or lower, wherein N1 is a water-resistant adhesive strength measured after stored at room temperature for one day, immersed in water for 30 minutes, taken out from the water and then residual water is wiped off; and has an N2 to N0 reduction rate of 40% or higher, wherein N2 is a water-peel strength measured after stored at room temperature for one day, 20 μL distilled water is dropped onto the adherend and is allowed to enter a PSA layer/adherend interfacial edge. N2 is measured at a tensile speed of 300 mm/min at a peel angle of 180°.

Abstract: Provided is an adhesive member to be adhesively fixed through pressure which has both position adjustability and adhesiveness and is capable of producing a sufficient adhesive strength in addition to the position adjustability. The adhesive member comprises a support, a pressure-sensitive adhesive layer provided on one surface of the support, and a plurality of protrusion elements arranged, in spaced-apart relation to each other, on a principal surface of the pressure-sensitive adhesive layer on a side opposite to the support. Each of the protrusion elements is composed of an aggregation of a plurality of cohesive particles, wherein the adhesive member has a frictional force of 0.4 N/cm2 or less, with respect to a stainless steel plate serving as an adherend, as measured when the protrusion elements are in contact with a surface of the adherend, and a shear adhesive strength of 45 N/cm2 or more.
