Abstract:
1. An electric double layer capacitor having a cell group containing a plurality of stacked electric double layer capacitor cells, and a circuit substrate electrically connected to each of the electric double layer capacitor cells contained in the cell group, comprising: electrode plates protruding from an end of each electric double layer capacitor cell and connected to electrodes of the electric double layer capacitor cell; a panel member fixed to the electrode plate; and a linear connection piece having a first end fixed to the panel member and a second end protruding away from the electrode plate; wherein the first end side of the linear connection piece is wound around by and fixed to a plate-shaped connection member while the connection member is fixed to the panel member, and the second end side of the linear connection piece is connected to the circuit substrate; and the connection piece and the connection member are fixed to a first end side of the panel member, and a second end side of the panel member is fixed to the electrode plate, such that the first end side of the panel member to which the connection piece and the connection member are fixed is movable with respect to the electrode plate.
