PROBLEM TO BE SOLVED: To provide an electricity storage system having a mechanism capable of positively connecting collector electrodes of capacitor cells, and of stably maintaining connection state over a long period. SOLUTION: In the electricity storage system 10 having a plurality of capacitor cells 151, in order to connect the capacitor cells in series, a coupling portion 160 of one of a pair of collector electrode 153, 154 in one capacitor cell and a coupling portion of another collector electrode among a pair of collector electrodes of another adjacent capacitor cell are arranged side by side in a line. A sheet of metal plate 162 having a plurality of protrusion 166 on its one surface is bent so that the surface having the projections opposes to form a pair of terminal holding pieces 163, 164 opposite to each other, and two coupling portions arranged side by side in a line are clamped and pressed by the pair of terminal holding pieces, so that the plurality of protrusion encroach into both the surfaces of the two coupling portions.
