て封止部材を固定した構造になっている。(Prior art) Aluminum electrolytic capacitors and electric double layer capacitors, for example, have four content elements housed in a metal case, the opening of the case sealed with a sealing material, and a part of the case made into a recess. It has a structure in which the sealing member is fixed.
(発明が解決しようとづる課題)
しかしケースの窪んだ部分は元に戻り易く、そのために
、封止部材とケースとの隙間から電解液が漏れ易くなる
欠点がある。(Problems to be Solved by the Invention) However, the recessed portion of the case tends to return to its original state, which has the disadvantage that the electrolyte tends to leak from the gap between the sealing member and the case.
本発明の目的は、以上の欠点を改良し、密封不良を防止
しうるケース入りコンデンサを提供するものである。An object of the present invention is to provide a cased capacitor that can improve the above-mentioned drawbacks and prevent poor sealing.

される。充填後に、加熱して高分子重合体4を硬化し、
ケース7を剥離する。As shown in FIG. 2, the polymer 4 is made by covering the recess 3 of the case 1 with a tape 7 and making holes 8 in a part of the tape 7.
By injecting the liquid through the hole 8, the hollow portion 3 is filled. After filling, the high molecular weight polymer 4 is cured by heating,
Peel off case 7.
上記実施例によれば、ケース1の窪み部3に高分子重合
体4が充填硬化されているために、窪み部3が元に戻る
のを防止できる。According to the above embodiment, since the polymer 4 is filled and hardened in the recess 3 of the case 1, the recess 3 can be prevented from returning to its original state.
なお、高分子重合体は、窪み部の一部に充填されていて
もよい、。Note that the high molecular weight polymer may be partially filled in the depression.
