[Brief explanation of the drawing]

FIG. 1 is an exploded perspective view of an electrode part of an embodiment of the present invention, FIG. 2 is a sectional view showing an example of an electric double layer capacitor element, and FIG. 3 is a sectional view showing a conventional example of an electric double layer capacitor. Fig. 4 is an exploded perspective view of the electrode section of the conventional example, Fig. 5 is a sectional view of the insulating plate in the conventional example, Fig. 6 is a sectional view of the insulating plate of the embodiment shown in Fig. A cross-sectional view of the electrode portion, and FIG. 8 is a perspective view for explaining another example of the electrode plate. In the figure, 24 is an insulating plate, 24a and 24g are annular ribs, 24b and 24f are recesses, 25 is a first electrode plate, 26 is a second electrode plate, and 25b and 26a are terminal portions.

Claims (1)

[Claims for Utility Model Registration] A laminate formed by stacking a plurality of electric double layer capacitor elements, an insulating plate disposed on the laminate, and a laminate electrically insulated from each other by the insulating plate. an electrode part having first and second electrode plates; a conductive case in which the laminate and the electrode part are housed; and a conductive case from which the first and second electrode plates are respectively drawn out of the conductive case. In the electric double layer capacitor, the upper surface and the lower surface of the insulating plate each include
An annular rib is formed on the outer periphery by making the area near the outer periphery thicker than the part where the recess is provided so as to form a recess with a diameter into which the first or second electrode plate is fitted. , and the first and second electrode plates are fitted into the recesses of the insulating plate.
