Abstract
A current interruption device includes a deforming plate, a contact plate and a conducting plate which configure a current path. The deforming plate includes one surface on an opposite side from the contact plate facing a first space, a pressure of which is retained to a same pressure as the internal pressure of the casing and the other surface opposed to the contact plate facing a second space, a pressure of which is retained to a same pressure as an external pressure of the casing. When the internal pressure rises above the predetermined level, the second contact portion is separated from the conducting plate by deformation of the deforming plate toward the contacting plate.
