    Abstract: A conductive pressure-sensitive adhesive tape contains an acrylic pressure-sensitive adhesive, a conductive filler, and a heating foaming agent. An acrylic polymer can be preferably used as the acrylic pressure-sensitive adhesive. With the multiple conductive fillers being electrically connected to each other, conductive paths communicating from one of the major surfaces of the tape to the other major surface thereof are formed before temperature sensing. The heating foaming agent is a heating-type foaming agent that is foamed by being heated. The electrical connection between the conductive fillers, which has been formed before the heating foaming agent is foamed, is disconnected by the foamed heating foaming agent, and the conductive paths communicating from one of the major surfaces of the tape to the other major surface thereof are eliminated.
