Abstract
An electrochemical reaction device comprises: an anode to oxidize water; an electrolytic solution flow path facing on the anode and through which an electrolytic solution containing the water flows; a cathode including: a porous conductive layer having first and second surfaces; and a reduction catalyst layer having a third surface disposed on the first surface and containing a reduction catalyst to reduce carbon dioxide; a separator between the anode and the cathode; a power supply connected to the anode and the cathode; and a flow path plate including: a fourth surface on the second surface; and a flow path facing on the second surface and through which the carbon dioxide flows. A ratio of an area of an overlap of the second surface and the flow path to an area of the second surface is 0.5 or more and 0.85 or less.
