Abstract
A cylindrical sealing member for a capacitor has a circular first plane and a circular second plane placed oppositely to the first plane, and is provided with two lead holes that penetrate the first and second planes. This sealing member for a capacitor contains butyl rubber, and inorganic material oblate particles having flat surfaces. The sealing member includes a first portion, and a second portion in the vicinity of an outer circumference of the sealing member as well as in the vicinity of the two lead holes. In the first portion, the inorganic material oblate particles are scattered such that flat surfaces thereof are oriented substantially in parallel with the first plane. In the second portion, the inorganic material oblate particles are scattered such that the flat surfaces thereof are oriented substantially perpendicularly to the first plane.
