欠点があつた。 Conventionally, this type of electrolytic capacitor has a crown-shaped metal cap 3 having a solderable metal surface on the outside as an external electrode at both ends of an insulating container 2 made of synthetic resin or the like that houses a capacitor element 1, as shown in FIG. Although crowned ones have been devised and tried,
Since the space between the insulating container 2 and the capacitor element 1 is small and 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 with an elastic body interposed. Moreover, since there were two fitting parts at both ends, there were drawbacks such as a lack of airtightness.

めに被覆された樹脂で省略してもよい。 FIG. 3 shows an anode external terminal 8, which is integrally formed with a cylindrical portion 9 press-molded from a chemically convertible metal such as aluminum and a prismatic portion 10.
A solderable metal layer of nickel, copper, etc. is formed on the surface by electroless plating, vapor deposition, etc., and solder plating is applied on top of the layer. Further, the prismatic portion 10 may be integrally formed by using a metal-plated rectangular plate made of copper, brass, etc., or by fitting a solderable metal crown to the cylindrical portion 9 and welding it to the cylindrical portion 9 described above. . FIG. 4 shows an electrolytic capacitor constructed using the above-mentioned cylindrical metal case 4, in which an anode tab 11 made of plate-shaped or linear aluminum or the like is welded to an anode electrode foil and a cathode electrode foil,
The cathode tabs 12 are connected to form a capacitor element 13 via a separator such as electrolytic paper. Next, an annular elastic body 14 is attached to the cylindrical portion 9 of the external terminal 8, and the external terminal 8 and the anode tab 11 are welded, and the bottom or inner surface of the metal case 4 and the cathode tab 12 are welded, respectively. The capacitor element 13 is impregnated with an electrolytic solution, and is housed in the metal case 4. At the same time, the external terminal 8 equipped with the elastic body 14 is fitted into the circular part of the opening 5 of the metal case 4. The opening 5 is tightened and sealed to complete the process. Reference numeral 16 is a resin coated on the body of the metal case 4 for insulation, and may be omitted.

が生ずる。 Therefore, the side surface 6 of the metal case 4 has a flat surface 7, and the wound capacitor element 13 is inserted into a polygonal cylinder surrounded by the flat surface 7.
A space 15 is formed between the metal case 4 and the capacitor element 13, and when the capacitor is in use, the impregnated electrolyte and the like are absorbed into this space 15 against heat generation inside the capacitor element 13 and rapid changes in ambient temperature.
By absorbing the expansion and contraction of the capacitor element 13 by moving in and out of the capacitor, the capacitor acts as a breather against temperature changes. Therefore, the electrolytic solution does not leak from the sealing part, and airtightness is significantly improved. The side surface 6 of the cylindrical metal case 4 has a flat surface 7, and one end surface of the external terminal 8 is arranged on an extended surface of the flat surface 7 of the metal case 4, as shown in FIGS. Because of this, it can be stably fixed when face bonding onto a printed circuit board and fixing it with an adhesive.
