ELECTROLYTIC CAPACITOR AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electrolytic capacitor which solves a subject that short-circuiting occurs under a high-temperature environment since heat resistance is low and is excellent in high dielectric strength, high heat resistance and long service life. SOLUTION: The electrolytic capacitor comprising a capacitor element provided with an anodic foil and a cathodic foil and a separator containing a driving high-molecular electrolyte complex 14 interposed therebetween and a metal casing in which the capacitor element is sealed, wherein the driving high-molecular electrolyte complex 14 is provided with the electrolyte and a copolymer of acrylates, and the electrolyte is incorporated in the copolymer of the acrylates and the metal casing is filled with an inert gas.
