Abstract

An electric storage device disclosed in the present application includes a casing, a first electrode terminal and a second electrode terminal that are provided on a terminal attachment wall of the casing, and an electrode assembly, a first conductive member, a second conductive member, and a current interruption device that are disposed within the casing. The first conductive member and the second conductive member connected respectively to a positive electrode or a negative electrode of the electrode assembly. The current interruption device is arranged between the terminal attachment wall and the electrode assembly, connected in series between the first electrode terminal and the first conductive member, and configured to connect or interrupt a conductive path from the electrode assembly to the first electrode terminal. A first spacer is further provided between the current interruption device and the electrode assembly, the first spacer being in contact with the electrode assembly.
