Abstract: A solid-electrolyte electrolytic device may be excellent in operation rate and have device life without stopping a CO2 reduction reaction. A solid-electrolyte electrolytic device may include: a cathode that performs a reduction reaction; an anode that constitutes one pair of electrodes together with the cathode; an electrolytic solution that is in contact with the anode and supports an oxidation-reduction reaction; a solid electrolyte that is disposed between the cathode and the anode; and a refresh unit that supplies a recovery liquid for diluting or replacing the electrolytic solution to the anode to remove a salt precipitated between the cathode and the solid electrolyte, the recovery liquid being a solution with a lower concentration of a cation identical to a cation included in the salt than the electrolytic solution.
