Polyimide precursor solution

The purpose of the invention is to provide a polyimide precursor solution having excellent environmental compatibility and good storage stability and leveling properties, the polyimide precursor solution making it possible to produce a polyimide molded article having excellent mechanical strength. The invention provides a polyimide precursor solution obtained by dissolving polyamic acid and a salt of a weakly basic compound having an acid dissociation constant (pKa) of 4.5-8.5 in a solvent containing a polyhydric alcohol.
