PROBLEM TO BE SOLVED: To provide a method for manufacturing an electrode wire for wire electric discharge machining which has high high-temperature tensile strength and excellent electric discharge machinability, and also to provide an electrode wire for wire electric discharge machining manufactured by using the method. SOLUTION: In a method for manufacturing an electrode wire 20 for wire electric discharge machining, a covered wire 30 having a Zn layer 32, and a Cu;32 to 37 wt.% Zn alloy layer 33 in this order on an outer circumference of a core 31 formed of Cu;0.05 to 0.2 wt.% Zr alloy is subjected to the diffusion heat treatment to form a wire 40 having a Cu-Zn alloy layer 42 of high Zn concentration on an outer circumference of a core 41, and the wire 40 is subjected to the aging precipitation treatment.
