CONNECTION MEMBER

摘要

TASK: Provided is a connection member which has a fusing characteristic as a fuse and which is able to efficiently absorb/disperse stresses relative to those displacements in three-dimensional directions between a storage element and the connection member which are caused due to vibration or the like. MEANS OF SOLVING THE PROBLEM: A connection member is a connection member configured to electrically connect respective storage elements to each other in a power storage device constituted by a plurality of storage elements. The connection member includes: a substrate; and a plurality of connecting portions connected to electrodes of the respective storage elements and configured to cut off electric connection with the storage elements by fusing at the time when a current of a predetermined value or more flows therein. The connecting portion is formed by performing punching on the substrate and includes at least two bent portions bent in a punching direction. One of the bent portions is bent along a first direction perpendicular to the punching direction, and the other one of the bent portions is bent along a second direction perpendicular to the punching direction and perpendicular to the first direction.
