Provided is a pressure-sensitive adhesive tape that has an excellent pressure-sensitive adhesive strength, and that can achieve both of adhesiveness to an adherend and peelability. The pressure-sensitive adhesive tape includes a base material; and a pressure-sensitive adhesive layer formed of an active energy ray-curable pressure-sensitive adhesive. A surface of the pressure-sensitive adhesive layer after active energy ray irradiation has a microphase-separated structure including an island portion and a sea portion having a storage elastic modulus higher than a storage elastic modulus of the island portion, in a storage elastic modulus mapping image obtained with an atomic force microscope.
