Abstract
Capacitor element ( ) formed by winding both anode and cathode electrode foils connected with lead terminal ( ) via a separator is placed in bottomed cylindrical shape outer case ( ) made of aluminum and the like. On the outer periphery of the round rod portion ( ) of the lead terminal is fitted tube ( ) made of a flexible material in a movable manner. The lead terminal fitted with the tube is drawn through sealing body ( ) fitted on the inner periphery of the opening of the outer case ( ) outside. The sealing body includes an elastic ring ( ) made of a flexible material, as fitted on the outer periphery of sealing plate ( ) made of a rigid material more rigid than the tube. The lead terminal fitted with the tube is inserted in each of a pair of through-holes ( ) provided on the sealing plate. Due to the pressure from the lead terminal during the insertion thereof in the through-hole, the tube deforms in an elongating fashion along the insertion direction, which works to allow the tube and the round rod portion to closely contact with each other and also allow the tube and the through-hole to closely contact with each other, so that the air tightness of the lead drawing part can be improved.
