Abstract:
1. An electrode foil comprising a metal foil having a thickness of from 1 μm to 250 μm, wherein the electrode foil comprises, on at least one outermost surface thereof, a light-scattering surface having a Pv/Pp ratio of 2.0 or higher, wherein the Pv/Pp ratio is a ratio of a maximum profile valley depth Pv of a profile curve to a maximum profile peak height Pp of the profile curve as measured in a rectangular area of 181 μm×136 μm in accordance with JIS B 0601-2001, and wherein the light-scattering surface has an arithmetic average roughness Ra of 60 nm or less as measured in accordance with JIS B 0601-2001.
