、陰極に起因する陰極容量も大きくする必要があり、金
属ケースの内面を粗面化して陰極の表面積を大ならしめ
る必要があった。Many of this type of small aluminum electrolytic capacitors are used for relatively low voltages, and since aluminum electrolytic capacitors can be configured with a large anode capacity per unit area, the cathode capacity caused by the cathode must also be large, and the metal case is It was necessary to roughen the inner surface of the cathode to increase the surface area of the cathode.
しかし、金属ケースの内面を粗面化し、かつその陰極容

箔５付アルミニウムケース２とする（第４図参照）。As shown in Figure 2A, an aluminum case 2 equipped with a cathode lead wire 7 and a band-shaped roughened aluminum cathode foil 5 are prepared, and the aluminum cathode foil 5 is inserted into the aluminum case 2 as shown in the opening of the figure. , As shown in the figure, an aluminum cathode foil 5 that is U-turned and bent in the length direction of the aluminum case is welded 8 to the bottom of the aluminum case 2.
At the same time, the aluminum case 2 is formed into a cylindrical shape along the inner surface of the aluminum case 2 to make a complete electrical connection, thereby forming an aluminum case 2 with an aluminum cathode foil 5 (see FIG. 4).
