Abstract
An electrolytic device includes: an electrolysis cell including: an anode; a cathode; a first flow path plate facing on the anode, the first flow path plate having a first recess defining an anode flow path through which a first liquid flows; a second flow path plate facing on the cathode, the second flow path plate having a second recess defining a cathode flow path through which a first gas flows; and a separator provided between the anode and the cathode. The second flow path plate has an uneven surface on an inner surface of the second recess. An arithmetic mean roughness of the uneven surface is 0.03 μm or more and 50 μm or less.
