Abstract
PURPOSE:To stabilize a characteristic in a high-frequency region by a method wherein anode foil and cathode foil between which a separator has been laid are wound, a core rod composed of foam rubber is arranged in a central cavity part and a winding end is fixed by using an adhesive tape composed of a thermocontractible resin film in order to suppress a resonant oscillation. CONSTITUTION:High-purity aluminum foil is roughened by etching; its surface area is expanded; in addition, a dielectric film is formed by anodic oxidation; anode foil and cathode foil using the aluminum foil formed in this manner are wound; a core rod 9 composed of foam rubber is arranged in a cavity part in the central part of a winding core. A winding end formed after winding the anode foil and the cathode foil together with a separator is fixed by using an adhesive tape 8 composed of a thermocontractible resin film. After that, a paste is impregnated; this assembly is housed in a case; an open end is sealed hermetically; a finished product is obtained. The resonance is not caused by an oscillation during actual use because a cavity does not exist; accordingly, 'a howling phenomenon by a capacitor' is not caused at all; a sound which is true to an original sound is reproduced in an audio appliance.
