PROBLEM TO BE SOLVED: To provide a method for producing the mixture solution of an aromatic polyamide with an aromatic polyamic acid, by which the stable mixture solution used as a precursor for formed products such as composite fibers or films comprising the aromatic polyamide and the aromatic polyimide is obtained. SOLUTION: This method for producing the mixture solution of the aromatic polyamide with the aromatic polyamic acid is characterized by heating a mixture comprising the solutions of the polymers and a water-azeotropic solvent to distil off water and the solvent in the system, while stirring the mixture.
