められる。In this case, the capacitor element 2 has a winding body 2' of anode and cathode electrode foils and a separator made of aluminum, and leads 2a and 2b drawn out from the winding body 2' have lug terminals 3a, A sealing plate 3 with 3b is attached in advance. Furthermore, a horizontal throttle groove 1a is formed in advance in the metal case 1 as a positioning member for the sealing plate 3. That is, as the capacitor element 2 impregnated with a predetermined electrolytic solution is housed in the metal case 1, the sealing plate 3 is positioned so as to be placed on the horizontal throttle groove 1a. Thereafter, as shown by the chain line in FIG. 5, the opening edge 1b of the metal case 1 is caulked toward the inside of the case 1.
上記のように、従来では予め横絞り溝Ｌａが形成されて
いる金属ケース１内にコンデンサ素子２を収納するよう
にしているため、陽極および陰極の電極箔とセパレータ
の巻回体２′の大きさは自ずとそれに制約されることに
なり、収納効率に限界があった。As mentioned above, conventionally, the capacitor element 2 is housed in the metal case 1 in which the lateral throttle groove La is formed in advance, so the size of the anode and cathode electrode foils and the separator winding 2' is Naturally, this meant that there was a limit to storage efficiency.

にしている。In order to achieve the above object, the present invention provides a capacitor in which a sealing plate is attached to a pair of leads drawn out from a wound body of anode and cathode electrode foils and a separator in a bottomed cylindrical metal case. After the element is housed, a horizontal aperture groove as a positioning member for the sealing plate is formed in a predetermined portion of the metal case above the capacitor element so as to protrude toward the inside of the metal case. After positioning the sealing plate in the groove, the open edge of the metal case is caulked toward the inside of the metal case.
金属ケース内にコンデンサ素子を収納したのちに、同金
属ケースに横絞り溝を形成するものであるため、従来に
比べて横絞り溝がない分、コンデンサ素子の収納効率を
高めることができる。After the capacitor element is housed in the metal case, a horizontal throttle groove is formed in the metal case, so compared to the conventional case, since there is no horizontal throttle groove, the storage efficiency of the capacitor element can be increased.
