PURPOSE: Provided is a polyimide precursor solution which comprises a plasticizer for imparting the flexibility to the polyimide precursor solution, weakening an intermolecular force and thus facilitating the motion of molecular chain, and which can reinforce the adhesion of the polyimide. CONSTITUTION: The polyimide precursor solution comprising 65-95 parts by weight of N-methyl pyrroline, 5-35 parts by weight of polyamic acid, 0-15 parts by weight of n-butyl cellosolve, and 0-20 parts by weight of ethyl cellosolve, is characterized by further comprising 0.1-5.0 parts by weight of plasticizer. The plasticizer is selected from the group consisting of dibutylphthalate, n-dioctyl phthalate. The amount of plasticizer is 3 wt%. The solution further comprises a surfactant.
