The present invention relates to a method of forming a precursor solution for metal organic deposition and a method of forming a superconducting thick film using the same. A first precursor comprising one rare earth element, a second precursor comprising barium, and a third precursor comprising copper are dissolved into acid to form a compound solution, the compound solution is dissolved into solvent to form a pre-precursor solution, and the solvent of the pre-precursor solution is evaporated to form a precursor solution with the increased viscosity. A sufficiently thick film can be formed without any cracking through only one-time coating.
