Claims

[Scope of utility model registration request]

(1) A sealing board having a lead wire extraction through hole with an outer diameter smaller than the inner diameter of the metal case housing the capacitor element and larger than the diameter of the internal lead wire of the capacitor element, with an outer diameter larger than the inner diameter of the metal case. and a sealing plate formed by laminating rubber plates having lead wire pull-out through holes smaller in diameter than the internal draw-out lead wires, with the lead wire pull-out through holes being arranged so that the rubber plates are on the inside of the metal case. An electrolytic capacitor that is fitted into an internal lead wire and formed by bending the open end of the metal case inward and sealing it.

(2) The electrolytic capacitor according to claim (1) of the utility model registration claim, wherein the sealing plate has a resin layer on the outside thereof.
