    Abstract: A cell module includes a plurality of cells that each have a cylindrical shape and include a positive-electrode terminal and a negative-electrode terminal disposed on one end of the cell. One of the terminals is located at a center, and the other terminal is located on a circumferential edge and is electrically connected to a side surface of a tube of each of the cells, a connection intervening member mounted on the other terminal includes a tab extending along the side surface of the tube and electrically connected to the side surface, and a hole that causes the center of the one end to be exposed. The plurality of cells make up a cell block where the one ends are oriented in an identical direction, and cells adjacent to each other are aligned in rows, on the one ends of the plurality of cells, a plate having electrical insulating properties is disposed, the plate is provided with a hole that causes the one end of each of the cells to be exposed and is further provided with a plurality of conductive members on a surface of the plate distant from the cells, the conductive members extend along the rows of the cells aligned, two of the conductive members are disposed for each cell block and include terminal connectors electrically connected to terminals, having identical polarity, of the cells in each cell block, and the other terminals are connected with the terminal connectors through the connection intervening member.

    Abstract: A power storage device includes a case, a power storage element, a band-shaped lead, and a sealing member. The sealing member includes an insulating gasket including a base part, and a conductive sealing plate. The sealing plate includes a displacement part. The displacement part of the sealing plate and the lead are electrically connected to each other. The displacement part is configured to be displaced in a direction away from the lead in response to an increase in an internal pressure of the case, thereby electrically disconnecting the displacement part and the lead from each other. The power storage device further includes displacement suppressing means disposed in the case and configured to suppress displacement of the lead when the displacement part is displaced in the direction away from the lead. Thus, it is possible to increase the operational reliability of a current interrupt device.
