<p>A pressure-sensitive adhesive tape which comprises a foam base and a pressure-sensitive adhesive layer formed on at least one surface of the base, wherein the foam base has a thickness of 120 µm or less, a strength at 25% compression of 160 MPa or higher, and a density of 0.4 g/cm3 or higher, and the average thickness-direction cell diameter of the foam base is 23-50 µm. Although thin, this pressure-sensitive adhesive tape not only can have excellent waterproofing properties due to the satisfactory conformability to the adherend and have such resistance to drop impacts that peeling of the pressure-sensitive adhesive tape or cracking of the foam base is less apt to occur upon dropping, but also makes it possible to attain such excellent reworkability that in case of a trouble, the component can be efficiently separated.</p> |
