Abstract
An aluminum electrolytic capacitor includes a capacitor element having lead terminals; an armor case housing the capacitor element; and a rubber seal having a terminal passage hole for the lead terminals drilled therein and mounted on an opening section of the armor case. A hole diameter of a lead wire passage hole is smaller than an outside diameter of an outside lead wire, and a conical guide surface of progressively smaller diameter is formed between a round bar mating hole and the lead wire passage hole within a terminal passage hole. A passage guide part of progressively smaller diameter from a lead wire body is integrally furnished at an end of the outside lead wire so as to have a smaller diameter than the hole diameter of the lead wire passage hole, forming a conical sloped surface having a predetermined angle on a peripheral surface of the passage guide part.
