摘要：
A method for producing an electrode foil includes an electrolytic etching step of etching a metal foil containing first metal by applying current between the metal foil and an electrode in etching liquid while a principal surface of the metal foil faces the electrode. A masking member is disposed between the principal surface of the metal foil and the electrode so as to cover a partial region of the principal surface. The masking member is an electric conductor. The masking member is electrically connected with the metal foil.
