An electrolytic capacitor including a capacitor element having an anode part and a cathode part, a cathode foil electrically connected to the cathode part, and a package body sealing the capacitor element. The capacitor element and the cathode foil are stacked together, constituting a stack in which the cathode part of the capacitor element is electrically connected to the cathode foil. The package body contains an epoxy resin. The thickness of the package body located above or below the stack in a stacking direction of the stack is 24.9% or more of the thickness of the stack in the stacking direction.
