Abstract: An electrode (1) includes a resin film (2), a metal underlayer (3), and a conductive carbon layer (4) in sequence in a thickness direction. A surface of the conductive carbon layer (4) has an arithmetic average roughness Ra of 1.50 nm or less and a skewness Rsk of 0.00 or more.

Abstract: An electrode includes a substrate film, a metal underlying layer, and a conductive carbon layer. A ratio (O/C) of oxygen to carbon at a place 4.5 nm away from a one-side surface of the conductive carbon layer toward the other side in the thickness direction is less than 0.01 where the ratio (O/C) of oxygen to carbon is measured using X-ray photoelectron spectroscopy.
