Kind Code:
A1
Abstract:
This secondary battery is provided with: an electrode assembly; a case that houses the electrode assembly; a negative electrode terminal that is fixed to the case; and a current cutoff part that constitutes a part of a conduction path between the electrode assembly and the negative electrode terminal and that cuts off the conduction path when the inner pressure of the case reaches a set pressure. The current cutoff part is provided with a contact plate that is joined to the negative electrode terminal. The secondary battery is provided with a first conductive member that constitutes a part of the conduction path and that is joined to a negative electrode tab group of the electrode assembly by a first joint, a second conductive member that constitutes a part of the conduction path and that is joined to the contact plate by a second joint, and a fixed part of the first conductive member and the second conductive member.
