た。 Conventionally, this type of electrolytic capacitor has a capacitor element 1 housed in an insulating container 2 made of synthetic resin, etc., with a crown-shaped metal cap 3 having a solderable metal surface on the outside at both ends, as shown in FIG. However, since the electrolyte leaks from the fitting part between the insulating container 2 and the crown-shaped metal cap 3, it is necessary to apply adhesive, and the fitting part is in two places at both ends. Because of this, airtightness was lacking.

る。 Fig. 2 shows an anode terminal 4, which is made of copper, brass, etc., and is integrally formed by welding a metal 5 whose surface is plated to enable soldering and a cylindrical metal 6 having chemical properties such as aluminum. ing. Third
The figure shows an elastic ring 7 made of rubber or the like having a substantially circular cross section and fitted onto the outer peripheral surface of the cylindrical metal 6. FIG. 4 shows a metal case 8 made of aluminum or the like, and a solderable metal cap 9 is welded to the periphery of the bottom. FIG. 5 is a completed sectional view of an electrolytic capacitor, in which an anode tab 10 and a cathode tab 12 are led out from the anode electrode foil and the cathode electrode foil, respectively, and the two electrode foils are placed facing each other through a separator such as electrolytic paper. The capacitor element 12 is formed by winding the capacitor element 12. Next, an elastic ring 7 is attached to the periphery of the cylindrical metal 6 of the anode terminal 4.
The capacitor element 12 is impregnated with an electrolytic solution by welding the metal 6 and the anode tab 10 and the bottom or inner surface of the metal case 8 and the cathode tab, and then storing it in the metal case 8. At the same time, the opening of the metal case 8 is tightened and sealed to complete the process.

できるなどの効果がある。 Therefore, an elastic ring 7 with a circular cross section is attached to the outer peripheral surface of the cylindrical metal 6 at the opening of the metal case 8, and the metal case 8 is tightened to seal the opening, thereby significantly improving airtightness. Even when it is mounted on a printed circuit board and soldered, the electrolyte leaks due to heating.
Extremely stable characteristics can be maintained without any increase in tan δ. In addition, since the elastic ring 7 has a circular cross section, it does not get stuck when inserted into the opening of the metal case 8, resulting in efficient production.
