<p>The present invention comprises: an electrode layered body (6), further comprising a cathode and an anode which are layered with a separator interposed therebetween; an external casing body (7) which houses the electrode layered body (6); an anode tab, one end whereof is electrically connected to the anode and the other end extended externally to the external casing body (7); and a current interrupt unit (10), further comprising a current interrupt element (11) which is positioned upon a current path between the anode and the anode tab. The current interrupt element (11) further comprises: a set of breaker units (16) which are linked on an interior surface which is opposite the external casing body (7) and which break when the external casing body (7) expands; and a blowout unit (17) which is formed astride the set of breaker units (16) and which blows out when excess current flows. One of the set of breaker units (16) is electrically connected to the anode tab, and the other of the set of breaker units (16) is electrically connected to the anode.</p> |
