ABSTRACT:
A capacitor includes a wound element, and externally take-out electrode members corresponding respectively to a first pole and a second pole and connected to each one of end faces of the wound element. This capacitor features that the wound element is positively fixed to the externally take-out electrode members, and has advantageously a small internal resistance. Collectors in inner circumference region of the wound element are bent in an opposite direction to a core of a winding shaft, and collectors in an outer circumference region are bent toward the core of the winding shaft. End faces of these collectors are connected to a lid, thereby forming a first pole of the capacitor, and end faces of those collectors are connected to a housing, thereby forming a second pole of the capacitor.
