<P>PROBLEM TO BE SOLVED: To stably improve the sealability of a sealing member. <P>SOLUTION: A sealing member for a capacitor is formed by an elastic material, has a shape of a circular column extending in an axial direction, and has a circular cross section formed in a direction perpendicular to the axial direction. Further, a pair of through holes is provided in parallel with the axial direction. A shape of the through hole on the cross section of the sealing member that is formed in the direction perpendicular to the axial direction includes a first arc protruding toward a circumference of the sealing member and a second arc protruding toward a center of the sealing member and having a curvature smaller than a curvature of the first arc. <P>COPYRIGHT: (C)2013,JPO&INPIT |
