<P>PROBLEM TO BE SOLVED: To provide a discharge surface treatment apparatus capable of enhancing the quality of a coating film C by the consistent discharge, and enhancing the machining efficiency of the discharge surface treatment. Ž<P>SOLUTION: A feed nozzle 29 is provided on an electrode holder 25 in a machining head 15. A feed nozzle 29 has a jet port 29m for jetting machining liquid toward a space between a fore end of a discharge electrode 23 and a machined portion Wa of a workpiece W. A suction duct 37 is provided on the machining head 15. The suction duct 37 has a suction port 37m for sucking the machining liquid between the fore end of the discharge electrode 23 and the machined portion Wa of the workpiece W, and is movable in the Z-axis direction relatively to the machining head 15 according to the consumption of the discharge electrode 23.
