Abstract
An adhesive tape includes a foam base and an adhesive layer disposed on at least one surface of the foam base, in which the foam base has a thickness of 120 μm or less, a 25% compressive strength of 160 MPa or more, and a density of 0.4 g/cmor more, and an average bubble diameter in a vertical direction of the foam base is 23 to 50 μm. Even though the adhesive tape has a small thickness, with this adhesive tape, it is possible to realize excellent waterproofness due to good conformability to an adherend, such drop impact resistance that detachment of the adhesive tape and cracking of the foam base at the time of dropping do not easily occur, and such excellent reworkability that a component can be efficiently separated even in the case where a problem occurs.
