摘要： Disclosed is a double-faced pressure-sensitive adhesive tape or sheet including a substrate and, respectively arranged on both sides thereof, two pressure-sensitive adhesive layers. The thickness from the surface of one of the.two pressure-sensitive adhesive layers to that of the other pressure-sensitive adhesive layer is 25 µm or less. The two pressure-sensitive adhesive layers have different adhesive strengths, and a pressure-sensitive adhesive layer having a lower adhesive strength has a tack in terms of ball number 3 or greater as determined according to the inclined type ball tack testing method specified in JIS Z 0237 at an inclination angle of 30°, a temperature of 23°C, and relative humidity of 65%. The substrate preferably has a thickness of 10 µm or less and more preferably has a thickness of 3 µm or less. Each of the two pressure-sensitive adhesive layers preferably has a thickness of 6 µm or less. The double-faced pressure-sensitive adhesive tape or sheet is thin, can securely affix adherends when applied, and can be easily separated from one of the adherends when peeled off.
