Abstract: The present embodiments provide a CO2 reduction catalyst which is used for a reduction reaction of carbon dioxide and shows a high efficiency in water, and a CO2 reduction electrode and a CO2 reduction device, which contain the CO2 reduction catalyst. This catalyst contains a conductive material and a porphyrin complex which has a specific structure and is insoluble in water. The porphyrin complex is insoluble in water because it contains only a small number of hydrophilic groups in its structure. The CO2 reduction electrode and the CO2 reduction device contain this catalyst.
