摘要： The present invention addresses a problem of providing an electrolytic capacitor with which an etching treatment of an electrode material is not required and with which it is possible to achieve higher capacitance than conventional electrolytic capacitors using electrode foils having surface areas increased only by etching. This electrolytic capacitor, as a solution, includes a capacitor element having an anode foil, a cathode foil, and separators interposed between the anode foil and the cathode foil; and an electrolytic solution impregnated in the capacitor element, wherein the anode foil or the cathode foil has a sintered material formed with sintered particles of power of at least one kind of aluminum and an aluminum alloy.
