Abstract: An electrode material including a conductive sheet containing carbon nanotubes having an average fiber diameter of 1 μm or less; a liquid inflow member that is formed on a first surface of the conductive sheet such that an electrolyte solution that is passed therethrough flows into the conductive sheet; and a liquid outflow member that is formed on a second surface of the conductive sheet and out of which flows the electrolyte solution that has passed through the conductive sheet; wherein, when using a sheet surface of the conductive sheet as a reference plane, the Darcy permeability, in an in-plane direction, inside the liquid inflow member, is at least 100 times the Darcy permeability, in a normal direction, through the conductive sheet.
