Film-forming composition

A film-forming composition comprising at least one selected from among a hydrolyzable silane compound, a hydrolysate of the compound, and a hydrolysis condensate of the compound, and a solvent, the film-forming composition being wherein:

• the hydrolyzable silane compound contains a hydrolyzable silane having a cyano group in the molecule and being of the following Formula (1):
• R1aR2bSi(R3)4−(a+b) (1)
• (wherein R1 is a group bonded to a silicon atom and is an organic group containing a cyano group;
• R2 is a group bonded to a silicon atom via an Si—C bond, and is each independently a substitutable alkyl group, a substitutable aryl group, a substitutable aralkyl group, a substitutable halogenated alkyl group, a substitutable halogenated aryl group, a substitutable halogenated aralkyl group, a substitutable alkoxyalkyl group, a substitutable alkoxyaryl group, a substitutable alkoxyaralkyl group, or a substitutable alkenyl group, or an organic group containing an epoxy group, an acryloyl group, a methacryloyl group, a mercapto group, an amino group, an amide group, an alkoxy group, or a sulfonyl group, or any combination of these;
• R3 is a group or atom bonded to a silicon atom, and is each independently a hydroxy group, an alkoxy group, an aralkyloxy group, an acyloxy group, or a halogen atom;
• a is an integer of 1;
• b is an integer of 0 to 2;
• and
• a+b is an integer of 1 to 3).
