Abstract

A film of zinc oxide electrochemically deposited from an aqueous solution is subjected to heat treatment at a temperature equal to or higher than 150° C. and equal to or lower than 400° C. in a nitrogen or inert gas atmosphere that contains oxygen, thereby obtaining a zinc oxide film that is low in electric resistance without impairing the light transmittance of the zinc oxide film.
