A capacitor of the present invention includes a hollow capacitor element prepared by winding a pair of flat electrodes with a separator sandwiched in-between in such a way that both ends of each respective electrode protrude in a direction opposite to each other, an electrode connecting member connected to each respective end surface of the electrode of the above, by metal plasma-spraying, welding, soldering and adhesion using a conductive adhesive, and a terminal for external connection is connected to the electrode connecting member. A cylindrical metal case contains the capacitor element together with a driving electrolyte and a sealing plate closing the opening of the metal case. A reduction in resistance of electrodes is made possible and, in addition, the capacitor can be made smaller in size and the number of the components can be decreased.
