To reduce a production cost by improving the constitution of an electrode in a fluid channel in an EHD pump, reducing a channel resistance of the EHD pump and simplifying a structure for arranging electrode.
In an electrohydrodynamic pump, a linear metal inside electrode is bridged in the inside longitudinal direction of a cylindrical metal outside electrode, exposing itself in the outside electrode, and the outer periphery of the inside electrode is surrounded with a liquid delivery channel tube extending outward of the outside electrode to form a liquid delivery channel. The exposed part of the inside electrode is made to face the inner peripheral surface of the outside electrode, the fluid, which generates dissociated ions when electric field acts, is introduced in the outside electrode and filled in between the outside electrode and the inside electrode, and a high DC voltage is applied between the inside electrode and the outside electrode.
