Abstract: A double-sided pressure-sensitive adhesive tape includes a support base member having a hand tearable property, a first acrylic adhesive layer on one surface of the support base member, and a second acrylic adhesive layer on another surface of the support base member. The first acrylic adhesive layer has a thickness t1 that is 5 μm or more and 50 μm or less, the second acrylic adhesive layer has a thickness t2 that is greater than the thickness t1 of the first acrylic adhesive layer and is 20 μm or more, the second acrylic adhesive layer has gel fraction X2 that is 20 mass % or more and 75 mass % or less, and the second acrylic adhesive layer has adhesive force greater than adhesive force of the first acrylic adhesive layer.

Abstract: A provided adhesive is a silicone-based adhesive having an initial adhesive force of 0.2 to 3 N/20 mm and having an adhesive force of 4 N/20 mm or less after heating at 260° C. for 30 minutes. A provided adhesive tape includes a cured layer of the above silicone-based adhesive. The adhesive tape may further include a substrate, and the cured layer may be provided on a surface of the substrate. The adhesive tape shows high adhesion performance and is capable of achieving low thermal dependence. The adhesive is capable of forming the adhesive tape.
