Abstract
A pump includes a flow passage through which a liquid containing an electrolytic solution is conveyed, a pair of electrodes in the flow passage to apply an electric field along the direction in which the liquid is conveyed, and a conductive member connected to one of the pair of electrodes and in contact with the liquid in the flow passage. The conductive member includes a sidewall portion that locally divides a flow of the liquid in the flow passage. The conductive member connected to one of the pair of electrodes may be a polyhedron or a column that is convex toward the electrode to which the conductive member is not connected.
