Summary: | To provide a highly reliable electrolyte capacitor.SOLUTION: An electrolytic capacitor comprises: a capacitor element comprising an anode on which a dielectric layer is formed; a conductive polymer which covers at least a part of the surface of the dielectric layer; and electrolytic solution including a non-aqueous solvent, a glycerin compound, and an ionic solute. The non-aqueous solvent is at least one selected from the group consisting of lactones, glycols, cyclic carbonates, and sulfones. The content of the glycerin compound in the electrolytic solution is 10 mass % or more and 50 mass % or less.SELECTED DRAWING: Figure 1
