Abstract: An electrolytic capacitor includes an electrode foil and a lead member connected to the electrode foil. The electrode foil has a first principal surface and a second principal surface opposite to the first principal surface. The electrode foil and the lead member are connected by a caulking part in an overlapping part in which the first principal surface of the electrode foil and the lead member overlap each other. The caulking part has a through-hole penetrating the electrode foil and the lead member. The electrode foil in the caulking part includes a first folded part that is folded back at a peripheral edge portion of the through-hole to be disposed on the second principal surface. The lead member in the caulking part includes (i) a penetrating part that penetrates the electrode foil and (ii) a second folded part that is folded back at an end portion of the penetrating part to be disposed on the second principal surface. The penetrating part includes an inner wall of the through-hole. The second folded part covers the first folded part.
