It consists of a hole and a small-diameter hole opening inside the case, and the gap between the electrode rivet inserted into the through-hole and the through-hole is formed by a large-diameter part inserted in the large-diameter hole and the large-diameter hole. In the sealing structure of an electrolytic capacitor, which is sealed by a sealing member made of a rubber-like elastic body, the tip of the small-diameter part of the sealing member is connected to the small-diameter part and inserted into the small-diameter hole. An elastic layer made of a rubber-like elastic material is provided that extends to the middle of the small diameter hole and covers the entire outer surface of the sealing body from its outer periphery, and the elastic layer is applied to the large diameter portion of the sealing member. A sealing structure for an electrolytic capacitor characterized by being formed integrally with.
