Abstract: An electrolytic capacitor includes a capacitor element. The capacitor element includes an anode part, a cathode part, and an intermediate part. The anode part includes a first portion that is a part of an anode body having a porous region, and a first dielectric layer. The intermediate part includes a second portion of the anode body, a second dielectric layer, and a first insulating member containing a first resin component. The cathode part includes a third portion of the anode body, a third dielectric layer, a solid electrolyte layer covering at least a part of the third dielectric layer, and a cathode lead-out layer covering at least a part of the solid electrolyte layer. The first resin component contains a curing product of a first reactive compound. At least a part of the first insulating member is disposed in pores of the porous region in the intermediate part.
