Abstract:
An electrode foil for an electrolytic capacitor including a metal porous portion, and a metal core portion continuous to the metal porous portion. When the metal porous portion is equally divided in three in a thickness direction of the metal porous portion into a first region, a second region, and a third region sequentially from the metal core portion side, the first region has a porosity P1, the second region has a porosity P2, and the third region has a porosity P3, satisfying P1
