Abstract
A current interrupt mechanism includes a partition wall defining a second space that is independent from a first space, and the partition wall includes a current path portion serving as a current path of a sealed battery. The current interrupt mechanism interrupts the current path in response to an internal pressure of the second space that is higher than a predetermined pressure. One conductive path passes through the current path of the current interrupt mechanism, and is in contact with the second electrolyte solution enclosed in the second space. Another conductive path includes a potential application line that is wired to the second electrolyte solution enclosed in the second space.
