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: In an adhesive material guiding apparatus, a nozzle configured to be disposed at a position facing an adherend as an object to be stuck is provided, and a path is configured such that a threadlike adhesive passes through a through hole formed in the nozzle. A braking member such as a top is disposed at an upstream side of the through hole of the nozzle. The braking member is configured such that at least one of the ease of sticking to the threadlike adhesive and a difficulty in slipping are superior to those of the through hole of the nozzle.
