摘要： A polyimide precursor solution includes a polyimide precursor having a weight average molecular weight within a range of 20000 to 80000, particles, and an aqueous solvent. The aqueous solvent contains an organic amine compound (A) (excluding a water-soluble organic solvent (B) described below), a water-soluble organic solvent (B) containing at least one selected from the group consisting of N-methyl-2-pyrrolidone, 1,3-dimethyl-2-imidazolidinone, N,N-dimethylformamide, and N,N-dimethylacetamide, and water (C). A content ratio [(A):(B):(C)] of (A), (B), and (C) is within a range of 0.02 to 0.07:0.02 to 0.05:0.88 to 0.96 in terms of mass ratio.
