    • A capacitor has a capacitor element, an electrolyte, a cylindrical case made of metal and having a bottom, a metal terminal plate, and a sealing rubber. The terminal plate has a body portion and a flange portion projected from an outer peripheral surface of the body portion toward the case. The sealing rubber is abutted onto the flange portion of the terminal plate, and is interposed between the outer peripheral surface of the body portion of the terminal plate and a side surface of the case for sealing the case. The case has a drawn and grooved portion formed by being drawn and thus grooved from an outside of the side surface at a place so that the sealing rubber is compressed between the outer peripheral surface of the body portion of the terminal plate and the case. Then, a ring-like groove is provided on the outer peripheral surface of the body portion of the terminal plate at a portion, which is padded with the sealing rubber, the sealing rubber is projected into the groove.

    • A capacitor includes a capacitor element including first and second electrodes, an electrolyte solution, first and second collector plates made of metal and joined to the first and second electrodes of the capacitor element, respectively, a case accommodating the capacitor element, the electrolyte solution, the first and second collector plates, a terminal plate placed at an opening of the case and joined to the second collector plate, and a sealing rubber sealing the terminal plate and the opening of the case. The case has a tubular portion and a bottom plate closing the tubular portion. An inner surface of the bottom plate of the case has a contacting portion contacting the first collector plate and a junction portion facing the first collector plate. The first junction portion of the inner surface of the bottom plate has a joining point joined to the first collector plate and a separation part facing the first collector plate around the first joining point by a first gap between the first junction portion and the first collector plate. The first collector plate is located away from the first contacting portion. The capacitor has a high reliability in connecting the electrodes, preventing an unnecessary resistance or a pin hole produced in the case.
    • 电容器包括电容器元件,其包括第一和第二电极,电解质溶液,金属制成的第一和第二集电板,分别与电容器元件的第一和第二电极接合,容纳电容器元件的壳体,电解质溶液, 第一和第二集电板,设置在壳体的开口处并接合到第二集电板的端子板,以及密封端子板和壳体的开口的密封橡胶。 壳体具有封闭管状部分的管状部分和底板。 壳体底板的内表面具有与第一集电板接触的接触部分和面向第一集电板的接合部分。 底板的内表面的第一接合部分具有接合到第一集电板的接合点和通过第一接合部分和第一集电板之间的第一间隙围绕第一接合点面对第一集电板的分离部分 。 第一集电板位于远离第一接触部分的位置。 电容器在连接电极时具有高的可靠性,防止了在该情况下产生的不必要的电阻或针孔。
