Abstract
A metal foil for capacitor element is produced through a process including steps of etching and ten electrochemically forming a metal foil after making cut lines each in a shape of a capacitor element with at least a part of a portion predetermined to be an anode-leading-out-part left uncut. The step of etching the foil is preferably performed with the anode-leading-out-parts being protected by protective material. Solid electrolytic capacitor elements prepared by using the metal foil have narrow variation in capacitance.
