The double-sided adhesive tape has satisfactory rollability, excellent reworkability after cleavage, and excellent shear holding characteristics at high temperatures. The double-sided adhesive tape includes a foam base, a resin layer (A1) disposed in direct contact with one surface of the foam base, an adhesive layer (B1) disposed on A1 on a side opposite to the foam base, a resin layer (A2) disposed in direct contact with another surface of the foam base, and an adhesive layer (B2) disposed on A2 on a side opposite to the foam base. A1 and A2 are each formed of a crosslinked product of a composition containing a resin having a hydroxy group and a compound reacting with the hydroxy group, and the tensile modulus of each of A1 and A2 is 50 MPa or more and 1000 MPa or less.
