A wire electrical discharge machining apparatus for machining a workpiece by supplying electric discharge energy to a gap between a wire electrode and the workpiece by machining-electric-power supplying section and by relatively moving the wire electrode and the workpiece by a positioning section has a fluid supplying section in which a working-fluid supplying section for supplying a working liquid to the gap, a mist supplying section for supplying a mist to the gap, a gas supplying section for supplying a gas to the gap, and a cooling-fluid supplying section for supplying the working liquid which is a cooling fluid for cooling the workpiece are combined and are formed integrally. It is possible to effect wire electrical discharge machining which is suitable for attainment of higher accuracy and higher quality.
