Abstract:
(EN) Provided is an electrode for electrolytic capacitors, which is capable of reducing leakage current. According to the present invention, an electrode 5 for an electrolytic capacitor 10 is provided with a metal foil 1 that has a valve action and a sintered layer 2 that is provided on one surface or both surfaces of the metal foil 1. The sintered layer 2 contains a sintered metal powder 3; the metal powder 3 has a valve action; and the amount of carbon contained in the electrode 5 is from 0.01% by mass to 0.2% by mass (inclusive).
(FR) L'invention concerne une électrode pour condensateurs électrolytiques, qui est capable de réduire le courant de fuite. Selon la présente invention, une électrode 5 pour un condensateur électrolytique 10 comprend une feuille métallique 1 qui a une action de valve et une couche frittée 2 qui est disposée sur une surface ou sur les deux surfaces de la feuille métallique 1. La couche frittée 2 contient une poudre métallique frittée 3; la poudre métallique 3 a une action de valve; et la quantité de carbone contenue dans l'électrode 5 est de 0,01 % en masse à 0,2 % en masse (inclus).
(JA) 漏れ電流を低減することができる電解コンデンサ用の電極が提供される。電解コンデンサ10用の電極5は、弁作用を有する金属箔1と、金属箔1の一方の表面又は両表面に設けられた焼結層2と、を備え、焼結層2が、焼結された金属粉体3を含み、金属粉体3が弁作用を有し、電極5に含まれる炭素量が、0.01質量%以上0.2質量%以下である。
