が大きくなり小型化し難く、高価となる欠点もあった。(Problems to be solved by the invention) However, the conventional cell has low sealing property,
In particular, there is a drawback that the electrolyte solution leaks out when it is non-aqueous. In addition, although metal having high strength such as stainless steel is used as the case material due to the hermeticity, it has a drawback that it is difficult to process, the caulking portion of the portion is large, it is difficult to downsize, and it is expensive.
本発明の目的は、以上の欠点を改良し、密閉性を向上

The present invention provides an electric double layer capacitor in which a spacer is placed, and the end portion is pressed by a case through the spacer to seal it.
（作用） 本発明によれば、セルの端部をケースにより押圧して
いるため、より密閉性が向上する。(Operation) According to the present invention, since the end portion of the cell is pressed by the case, the hermeticity is further improved.
（実施例） 以下、本発明を図示の実施例に基づいて説明する。(Examples) Hereinafter, the present invention will be described based on illustrated examples.

圧している。In FIG. 1 and FIG. 2, 1 is a basic button type cell, in which the polarizable electrode 2 is separated by a separator 3 and housed in a stainless steel case, and the end 4 is separated by a separator 3 and a polypropylene member 5. It was crimped through.
6 is a case made of stainless steel, which accommodates two stacked cells 1 and has lead-shaped terminals 7 drawn out. Reference numeral 8 denotes an insulating spacer inserted between the end portions 4 of the cell 1 and between the end portions 4 and the case 6. The end 4 of the cell 1 is pressed by the end 9 of the case 6 via the spacer 8.

ている。Reference numeral 10 denotes a spring material, which is inserted between the inner surface of the case 7 and the cell 1 to fix the cell 1 to the case 6. 11 is cell 1
The lead-shaped terminal 13 is a terminal plate that is pressed against the inner surface of the case 6 via the insulating plate 12 while being brought into contact with one surface of the terminal.
上記実施例によれば、セル１の端部４が自らかしめら
