Zusammenfassung:	A film-forming composition for use in a coating diffusion method, capable of diffusing a dopant at a higher concentration, and further capable of concomitantly forming a silica-based coating film is provided. A film-forming composition for constituting a diffusion film provided for diffusing a dopant element into a silicon wafer, the film-forming composition including: (A) a polymeric silicon compound; (B) an oxide of the dopant element, or a salt including the dopant element; and (C) porogene.
