Abstract

A cathode part of an electrochemical reaction device comprises a conductor, a porous body, a reduction catalyst, an electrolytic solution flow path, a first flow path, and a second flow path. The conductor has a conductive surface. The porous body includes a first surface, a second surface, a first porous portion, and a second porous portion. The first surface is in contact with the conductive surface. A contact angle between an inner wall of the second porous portion and water is higher than a contact angle between an inner wall of the first porous portion and the water. The reduction catalyst is supported on the second surface to reduce carbon dioxide. The electrolytic solution flow path faces the reduction catalyst. The first flow path faces the first porous portion. The second flow path faces the second porous portion.
