The present invention relates to a manufacturing method of a polyimide. The manufacturing method of the polyimide comprises the steps of: adding one or more species of dianhydride monomers, one or more species of diamine monomers, catalysts and dehydrators into water; and conducting the reaction of the same. Unlike original techniques, the manufacturing method doesn′t use organic solvents and the reaction conditions are relatively mild because the method uses the water as the solvents. Further, the manufacturing method is eco-friendly and economical as the method has no problems of recovery or disposal of the organic solvents. Furthermore, manufacture of the polyimide simply is possible thanks to decrement of synthesis stages of the polyimide.
