Provided is a connection member that has a fusing characteristic as a fuse and that is able to effectively absorb and distribute stress with respect to three-dimensional displacement between a storage element and the connection member due to vibration or the like. The connection member electrically connects storage elements in a storage device comprising a plurality of storage elements. The connection member is provided with: a substrate; and a plurality of connection parts that are connected to the electrodes of the storage elements and that are fused when an electric current of a prescribed value or greater flows, thereby disconnecting the electrical connections with the storage elements. The connection parts are formed by stamping the substrate and have at least two folded parts that are folded in the direction of the stamping. One of the folded parts is folded along a first direction that is orthogonal to the stamping direction, and the other folded part is folded along a second direction that is orthogonal to the stamping direction and orthogonal to the first direction.
