Abstract
A resist film removing composition used in the manufacture of a thin film circuit element having an organic insulation film which comprises 50 to 70% by weight of an alkanolamine having 3 or more carbon atoms, 20 to 30% by weight of a water-miscible solvent and 10 to 20% by weight of water. The resist film removing composition can easily remove a resist film remaining after etching, without swelling the organic insulation film.
