PROBLEM TO BE SOLVED: To provide an electrolytic capacitor which can inhibit characteristic change even after long term use under a high temperature environment.SOLUTION: An electrolytic capacitor includes: a cylindrical case having an opening at one end and extending in an axial direction; a capacitor element which is stored in the case with an electrolytic solution; a sealing body attached to the opening of the case; a seat plate which covers the opening with an opening side end part of an outer peripheral surface of the case; and an annular packing attached to an outer periphery of the case. The seating plate contacts with the outer peripheral surface of the case and the opening side end part of the case and covers at least part of the annular packing while contacting therewith from the radial outer side.SELECTED DRAWING: Figure 3 【課題】高温環境下で長期間使用しても特性変化を抑制できる電解コンデンサを提供する。【解決手段】一端に開口部を有し軸方向に延びる筒状のケースと、前記ケース内に電解液とともに収納されるコンデンサ素子と、前記ケースの開口部に装着される封口体と、前記開口部を前記ケースの外周面の前記開口部側の端部とともに覆う座板と、前記ケースの外周に取り付けられる環状パッキングと、を備え、前記座板は、前記ケースの外周面及び前記ケースの開口部側の端部と接触しており、前記環状パッキングの少なくとも一部を径方向外側から接触しつつ覆っていることを特徴とする電解コンデンサ。【選択図】図３
