Abstract: An electro-conductive pressure-sensitive adhesive tape comprises a pressure-sensitive adhesive layer containing a resin component and an electro-conductive particle. The electro-conductive particle has at least one peak top existing in a particle size range from about 15 μm or more to about 50 μm or less and at least one further peak top existing in a particle size range from about 1 μm or more to about 12 μm or less in a particle size distribution curve thereof. The electro-conductive particle is contained in the pressure-sensitive adhesive layer in an amount of 40 mass % or more but 80 mass % or less, and has a true density in a level of larger than zero but smaller than 8 g/cm3.

Abstract: A pressure-sensitive adhesive sheet includes a pressure-sensitive adhesive layer and a base including a metal layer and a resin layer, and a product of an initial elastic modulus of the base and a total thickness of the base is 3000 N/mm or less, and a separation distance is 2 mm or less, the separation distance is measured with a peel test with a constant load as follows: a test piece of the pressure-sensitive adhesive sheet having a 10 mm width and a 100 mm length is attached to a surface of a stainless steel test plate and then, the test plate is left standing at a temperature of 23° C. for twenty four hours and then, a load of 100 gf is applied to one end of a length dimension of the test piece vertical to the surface of the test plate and a separation distance of the test piece is measured after one hour.

Abstract: A thermally-conductive pressure-sensitive adhesive sheet including a pressure-sensitive adhesive layer containing thermally-conductive particles. One side of the sheet is an adhesive face, and the other side is a non-adhesive face. The thermally-conductive pressure-sensitive adhesive sheet may include a non-adhesive layer on or over only one side of the pressure-sensitive adhesive layer. In this case, the ratio of the thickness of the non-adhesive layer to the thickness of the pressure-sensitive adhesive layer is preferably 0.04 to 0.6. The thermally-conductive pressure sensitive adhesive sheet preferably has a thermal resistance of 6 K·cm2/W or less. The thermally-conductive pressure sensitive adhesive sheet preferably has a total thickness of 50 to 500 μm.

Abstract: A pressure-sensitive adhesive sheet includes a pressure-sensitive adhesive layer and a substrate layer configured to support the pressure-sensitive adhesive agent layer. The pressure-sensitive adhesive layer has a storage modulus of 250 kPa or less at 23° C. The substrate layer has an elastic modulus of 1680 N/cm to 3000 N/cm both inclusive. The pressure-sensitive adhesive sheet shows a deviation amount less than 1.0 mm. The amount is the deviation amount of the pressure-sensitive adhesive sheet per 250 gf/cm2 of the sheet in a holding ability test at 80° C. after one hour from a time when the test is started.
