A polyimide precursor composition contains a polyimide precursor and an organic solvent. The polyimide precursor has a structural unit into which a specific xanthene structure has been introduced. The imidization ratio of the polyimide precursor is 10 mol % or more and 100 mol % or less. The organic solvent may be one or more solvents selected from N-methyl-2-pyrrolidone, 1-butyl-2-pyrrolidone, 3-methoxy-N,N-dimethylpropanamide, 3-butoxy-N,N-dimethylpropanamide, N,N-dimethylpropionamide, N,N-diethylformamide and 1,3-dimethyl-2-imidazolidinone.
