Abstract

The present invention aims to provide a cathode electrode which prevents an increase in hydrogen selectivity even if the catalyst layer is immersed in an electrolyte solution and enables a catalytic reaction for producing olefin-based hydrocarbons such as ethylene and alcohols such as ethanol through the carbon dioxide reduction reaction to be stably sustained with high efficiency over a long period. A cathode electrode which electrically reduces carbon dioxide, the cathode electrode comprising: a first layer with a first thickness, located on a surface layer of the cathode electrode; and a second layer with a second thickness, adjacent to the first layer in a thickness direction, wherein: the first layer contains copper; the first layer is surface-modified with a cation exchange substance substituted with a metal ion; and the second layer is a mixed layer of copper and carbon.
