PURPOSE: A method for manufacturing an electrochromic layer containing prussian blue for the electrochromic device and a method for manufacturing a thin film electrode comprising the same are provided to improve stability, durability and color contrast ratio of the electrochromic layer. CONSTITUTION: Insoluble prussian blue nano particles are synthesized(S100). The prussian blue nano particles can be solved by increase in surface charges of prussian blue nano particles(S120). Sol coating solution is manufactured by mixing the prussian blue nano particles, binder and polar solvent(S140). The sol coating solution is coated on a flexible substrate(S160). Heat treatment is performed on the flexible substrate(S180).
