Zusammenfassung:	Provided is a polyimide precursor composition that has excellent stability and that enables production of a polyimide film/substrate laminate having less warpage. The polyimide precursor composition contains: a polyimide precursor; a phenyl group-containing linear siloxane compound that has a refractive index of 1.54 or greater and that is contained in an amount more than 0.5 parts by mass but less than 30 parts by mass with respect to 100 parts by mass expressed in terms of polyimides of the polyimide precursor; and a solvent.
