PROBLEM TO BE SOLVED: To provide an electrode wire for wire electric discharge machining having high high temperature tensile strength, satisfactory wire drawing machining property, and satisfactory electric discharge characteristic. SOLUTION: This electrode wire 1 for wire electric discharge machining is constituted such that a Cu-Zn alloy covered layer 3 having a ratio of a layer thickness (t) to an outside diameter D of the electrode wire 1 (t/D) of 0.05 to 0.2 is formed at outer periphery of a core wire 2 having an outside diameter of 0.07 mm or less, containing Ag of 1.0 to 35 wt.%, and forming a remaining part by alloy composed of Cu and unavoidable impurities.
