Abstract: The present invention provides an electrolytic capacitor which is increased in vibration resistance by making it possible to fix the capacitor element strongly in the outer case, without adversely affecting electrical characteristics of the capacitor element. In an electrolytic capacitor in which a capacitor element obtained by winding electrode foils with a separator therebetween and winding a winding stop tape on an outer circumferential surface thereof to stop the winding is inserted in an outer case and the outer case is sealed with a sealing member, a width of the winding stop tape is greater than or equal to a width of the electrode foils, and the capacitor element is press-fixed by an internal bottom surface of the outer case and the sealing member.

Abstract: A water-tight rubber or plastic insulated cable includes water-tight compound which is injected into apertures among stranded wires for a conductor. The stranded conductor is compressed to have a solidity factor of 85 to 95% of the conductor. The water-tight compound is injected into the apertures among the stranded wires except for an outermost surface of the conductor. The water-tight compound has a scorch time of more than 20 minutes under a temperature of 130.degree. C. and includes conductive carbon of 50 to 60 weight %.
