To provide a silicaceous film forming composition capable of forming a silicaceous film having low permittivity, excellent bondability, and sufficient mechanical strengths.
The silicaceous film forming composition comprises a component (a): a siloxane resin prepared by hydrolytically condensing a compound represented by formula (1); R1nSiX4-n (wherein R1 is H, F, a group containing B, N, Al, P, Si, Ge, or Ti, or a 1-20C organic group; and X is a hydrolyzable group; and n is an integer of 0-2, provided that R1s may be the same or different from each other when n is 2; and Xs may be the same or different from each other when n is 0-2), a component (b): a solvent which can dissolve component (a), and a component (e): a polymer having hydroxyl-containing side chains, wherein the polymer satisfies the relationship represented by formula (2); 0MOH0.410-2 (wherein MOH is the concentration (mol/g) of the hydroxyl groups of the polymer).
