ELECTRICAL CAPACITOR, ELECTRICAL CAPACITOR MODULE, FABRICATION METHOD OF THE ELECTRICAL CAPACITOR, AND FABRICATION METHOD OF THE ELECTRICAL CAPACITOR MODULE

摘要

An electrical capacitor includes: a band-shaped coating foil for positive electrode having a non-coated part of which an edge of one longitudinal side is not coated with an active material; a band-shaped coating foil for negative electrode having a non-coated part of which an edge of one longitudinal side is not coated with an active material; and a band-shaped separators through which an electrolysis solution and ions can pass. The coating foil for positive electrode and the coating foil for negative electrode are flatly wound via the separators so that the non-coated part in the side of the coating foil for positive electrode and the non-coated part in the side of the coating foil for negative electrode are exposed in opposite sides to each other, and the electrode group of the non-coated parts exposed to both sides are bonded.
