Title:
ELECTRODE FOIL PRODUCTION METHOD AND CAPACITOR PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/094219
Kind Code:
A1
Abstract:
This electrode foil production method comprises an electrolytic etching step wherein an electrode is made to face at least one main surface of a metal foil that includes a first metal and, in an etching liquid, a current is passed between the metal foil and the electrode and the metal foil is etched. The electrode foil production method is characterized in that a masking member is arranged between the main surface of the metal foil and the electrode so as to cover one region of the main surface, in that the masking member is a conductor, and in that the masking member and the metal foil are electrically connected.
