Abstract: An electrode foil for an electrolytic capacitor includes an anode electrode body including a base material part having a porous body portion, and a dielectric layer disposed on a surface of the porous body portion. The anode electrode body has a first main surface in which pores of the porous body portion are opened, a second main surface opposite to the first main surface, and an end surface connecting the first main surface and the second main surface. In the porous body portion, a first film thickness of the dielectric layer in an end surface vicinity region is larger than a second film thickness of the dielectric layer in a deep inner region, the end surface vicinity region being a region within a predetermined distance from the end surface, the deep inner region being a region located away from the first main surface and at a central portion in a direction parallel to the first main surface.
