PURPOSE: Provided are a silicone resin having good solubility and stability and used in forming nanoporous film, and a production method thereof. CONSTITUTION: A nanoporous silicone resin is a reaction product obtained by reacting a mixture containing (A) 15-70 mol.% of a tetraalkoxysilane of the formula: Si(OR1)4, (B) 12-60 mol.% of a hydrosilane of the formula: SiX3 and (C) 15-70 mol.% of an organic trialkoxysilane of the formula: R2Si(OR3)3, in the presence of (D) water, (E) a hydrolysis catalyst and (F) an organic solvent for the reaction product. In the formulae, each R1 is independently selected form C1-C6 alkyl groups; each X is independently selected from hydrolyzable substituents; R2 is C8-C24 hydrocarbon group or substituted hydrocarbon group including C8-C24 hydrocarbon chain; and each R3 is independently selected from C1-C6 alkyl groups.
