Abstract
Provided herein is a capacitor in which an electrolyte is infiltrated into a wound electrode group faster than conventionally. A negative current collecting member 9 has one slit 57 formed to extend across a protruded portion 49 and a negative current collecting member body (first welding portion) 53 and to penetrate the protruded portion 49 and the negative current collecting member body 53 in a thickness direction. The slit 57 passes through the center of the protruded portion 49, and extends entirely across the protruded portion 49 such that both ends of the slit 57 reach the negative current collecting member body 53.
