摘要： The present invention relates to a metal nanowire having a core-shell structure, the metal nanowire being conductive and transparent while having excellent oxidation stability, and being capable of maintaining excellent oxidation stability even after a secondary process using the metal nanowire of the present invention. Specifically, the metal nanowire having a core-shell structure, according to the present invention, comprises a core containing copper, and a shell containing silver on the core, wherein the ratio (D/L) of the diameter (D) of the core to the thickness (L) of the shell is 10-60, the thickness of the shell is 5-40 nm, and the peak intensity (I1) of Ag 3d5/2 of silver and the peak intensity (I2) of Cu 2p3/2 of copper in the X-ray photoelectron spectrum satisfy the following Equation 1.
