In general, an electrolytic capacitor is manufactured by connecting a flat inner drawer 2 to an anode and a cathode electrode foil 1 by crimping or the like, as shown in FIG. After this, the capacitor element 4 is impregnated with an electrolytic solution.

However, when connecting the internal lead 2 to the electrode foil 1 as described above, in the current method, as shown in FIG. Because of the cutting process, the corners 9 may become crisp or warped, or when winding the electrolytic paper at the right angles, the electrolytic paper 3 may be torn, causing a short circuit between the anode foil and the cathode foil. It was no longer useful as a capacitor.

このようなことからコンデンサを完成しても充分な特性
のものが得られなかったり、また製貧の歩留を著しく悪
いものにしていた。
For this reason, even if a capacitor is completed, it may not have sufficient characteristics, and the manufacturing yield may be extremely poor.

本考案は上述の欠点を排除し、信頼性の向上、歩留の向
上を図ったコンデンサを提供しようとするものである。
The present invention aims to eliminate the above-mentioned drawbacks and provide a capacitor with improved reliability and yield.

以下、本考案を第4図および第5図に示す実施例ついて
説明する。
The present invention will be described below with reference to the embodiments shown in FIGS. 4 and 5.

まず平板状の内部引出リード12を切断するとき第4図

角部のみでもよく、また同図口のように全体に半円状で
もよい。
First, when cutting the flat internal lead 12, the end of the lead plate 12 on the side connected to the electrode foil 11 is shaped into an arc, as shown in FIG. It may be only the corner part, as shown in the figure, or it may be semicircular as a whole, as shown in the figure's mouth.

特に自動リード板送り機構を用いた自動加締装置におい
ては、第5図に示すように定寸法に切断するときの切断
刃を円弧状にしておくだけでよい。
Particularly in an automatic caulking device using an automatic reed plate feeding mechanism, it is only necessary to make the cutting blade arc-shaped when cutting into a fixed size, as shown in FIG.

すなわち、平板状の内部引出リードの一方の先端角部を
円弧状に形威し、かつその他方端に相対する凹円弧状と
することにより、円弧状端は電極箔と接続され、他方端

となり、自動化を進める上で極めて効果がある。
That is, by forming one end corner of the flat internal lead-out lead into an arc shape and forming a concave arc shape opposite the other end, the arc-shaped end is connected to the electrode foil, and the other end is connected to the electrode foil. Since it has a concave arc shape, it is easy to position the rivet hole when machining the rivet hole at the connection part with the external terminal, and the hole is uniform without deviation, which is extremely effective in promoting automation.

次いで上述の陽極および陰極の電極箔11に電解紙3を
