る。Prior Art A conventional aluminum electrolytic capacitor was constructed as shown in FIG. In other words, the surface area is expanded by electrochemically roughening a metal with valve action, such as aluminum, and a dielectric film is formed on this surface by anodic oxidation to form an anode body, which is opposed to a cathode body. The capacitor element 1 is constructed by overlapping and winding foils with a separator in between and impregnating the foil with a driving electrolyte (hereinafter referred to as paste). The wire 2 is passed through a sealing rubber 3 and is housed in a cylindrical metal case 4 with a bottom, and the open end of the metal case 4 is sealed with the sealing rubber 3.

った。Problems to be Solved by the Invention When using audio equipment mounted with such conventional aluminum electrolytic capacitors, aluminum electrolytic capacitors use adhesive tape made of thermoplastic adhesive at the end of the winding. The tightening of the capacitor element becomes loose and the electrode foil vibrates, causing what is called "capacitor squeal".
It appears as a phenomenon. This phenomenon causes the distance between the electrodes of the aluminum electrolytic capacitor to become undefined, causing various distortions, making it unsuitable for audio equipment that aims to reproduce faithful sound.
本発明はこのような従来のアルミ電解コンデンサの鳴き
現象の問題点を解決するものである。The present invention solves the problem of the squeaking phenomenon of conventional aluminum electrolytic capacitors.

A capacitor element is constructed by impregnating it with an electrolytic solution, and is housed in a bottomed cylindrical case, and the open end is sealed with a sealing member.
