Title (EN) ELECTRODE FOIL PRODUCTION METHOD AND CAPACITOR PRODUCTION METHOD
(FR) PROCÉDÉ DE PRODUCTION D'UNE FEUILLE D'ÉLECTRODE ET PROCÉDÉ DE PRODUCTION D'UN CONDENSATEUR
(JA) 電極箔の製造方法およびコンデンサの製造方法
Abstract:
(EN) 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.
(FR) L'invention concerne un procédé de production d'une feuille d'électrode qui comprend une étape de gravure électrolytique consistant à amener une électrode en face d'au moins une surface principale d'une feuille métallique qui comprend un premier métal et à faire passer, dans un liquide de gravure, un courant entre la feuille métallique et l'électrode, et à graver la feuille métallique. Le procédé de production d'une feuille d'électrode est caractérisé en ce qu'un élément de masquage est placé entre la surface principale de la feuille métallique et l'électrode de façon à recouvrir une région de la surface principale, en ce que l'élément de masquage est un conducteur, et en ce que l'élément de masquage et la feuille métallique sont électriquement connectés.
(JA) 本発明に係る電極箔の製造方法は、第1金属を含む金属箔の少なくとも一方の主面に電極を対向させた状態で、エッチング液中において、前記金属箔と前記電極との間に電流を流して、前記金属箔をエッチングする電解エッチング工程を備える、電極箔の製造方法であって、前記金属箔の前記主面と前記電極との間に、前記主面の一部の領域を覆うようにマスキング部材が配置されており、前記マスキング部材が、導電体であり、前記マスキング部材と前記金属箔とが電気的に接続されていることを特徴とする。
