摘要： An object of the present invention is to rapidly produce condensates of various silane compounds containing different organic substituents by accelerating condensation reactions of the silane compounds containing hydrolyzable silyl groups without using acid or base catalysts. The present invention relates to a method for producing a siloxane resin, including: hydrolyzing and condensing a silane compound (B) containing a hydrolyzable silyl group represented by formula (I) below using a neutral salt (A) as a catalyst, the formula (I) being: R n SiX 4-n wherein R represents an organic group having a carbon atom directly bonded to Si; X represents a hydroxyl group or a hydrolyzable group; and n represents an integer of 0-3, provided that when n is 2 or greater, each R may be the same as or different from each other, and when (4-n) is 2 or greater, each X may be the same as or different from each other.
