Disclosed herein are a core-shell nano particle for formation of a transparent conductive film, a manufacturing method of the core-shell nano particle, and a manufacturing method of a transparent conductive film using the core-shell nano particle and, more particularly, a core-shell structured nano particle consisting of a core including indium or indium oxide and a shell including tin, a manufacturing method of the core-shell structured nano particle, and a manufacturing method of a transparent conductive film including (i) dispersing a core-shell structured nano particle into a solvent to manufacture a coating liquid, (ii) applying the coating liquid onto a substrate to form a coating layer, (iii) drying the coating layer, and (iv) performing an annealing process on the coating layer.
