PROBLEM TO BE SOLVED: To obtain a film-forming composition which has a low dielectric constant and an excipient mechanical strength useful for an interlayer insulating film of an electronic device, etc. , and forms an interlayer insulating film having an excellent film stability with time. SOLUTION: The film-forming composition comprises (A) a compound having a cage type structure and (B) a compound containing a group represented by general formula (1) (wherein, Ar<SB>1</SB>and Ar<SB>2</SB>are each an aromatic hydrocarbon group and may be mutually the same or different). The coating solution composed of the film-forming composition is used to give the interlayer insulating film of an electronic device and an electronic device having the insulating film as a layer constituent layer.
