Abstract
A current interruption device includes: a first conducting plateconfigured to be electrically connected to a terminal; and a second conducting platedisposed to face the first conducting plate and configured to be electrically connected to the electrode assembly. A center portion of the first conducting plateand a center portion of the second conducting plateare joined by a first welding portion. The second conducting plateis configured to be fractured so as to interrupt the current flowing between the terminal and the electrode assembly when the internal pressure of the casing exceeds the preset pressure. The first welding portion has a fuse function of interrupting the current flowing between the terminal and the electrode assembly by fusion of the first welding portion when the current flowing between the terminal and the electrode assembly exceeds a preset current.
