ELECTRICAL CAPACITOR, ELECTRICAL CAPACITOR MODULE, METHOD OF MANUFACTURING ELECTRICAL CAPACITOR, AND METHOD OF MANUFACTURING ELECTRICAL CAPACITOR MODULE

摘要

PROBLEM TO BE SOLVED: To provide an electrical capacitor having a low internal resistance and the capacity of which can be increased easily, and to provide an electrical capacitor module, a method of manufacturing an electrical capacitor, and a method of manufacturing an electrical capacitor module.SOLUTION: An electrical capacitor 1 includes a strip coating foil 3 for positive electrode having an uncoated part 3a not coated with an active material at the edge on one side in the longitudinal direction, a strip coating foil 2 for negative electrode having an uncoated part 2a not coated with an active material at the edge on one side in the longitudinal direction, and strip separators 4, 5 through which an electrolyte and ions can pass. The coating foil 3 for positive electrode and coating foil 2 for negative electrode are wound in flat shape via the separators 4, 5, so that the uncoated part 3a on the side of the coating foil 3 for positive electrode and the uncoated part 2a on the side of the coating foil 2 for negative electrode are exposed on the opposite side to each other. Electrode groups at the uncoated parts 2a and 3a exposed on both sides are bonded.
