PURPOSE: Provided are a silicate polymer excellent in crack resistance, mechanical strength, film-forming property, and dielectric property, a method for preparing the same, and an insulation film containing the same. CONSTITUTION: The silicate polymer is a condensate which is obtained by hydrolyzing a) a linear organic silane oligomer represented by formula 1, and b) a silane compound selected from the group consisting of a compound represented by formula 2, a compound represented by formula 3, and mixture thereof. In the formulae, each of R1 is independently hydrogen, alkyl, allyl, aryl, chlorine, acetoxy, hydroxy, or unsubstituted or substituted, linear or branched alkoxy having 1-4 carbon atoms(wherein the substituent is fluorine), R2 is independently hydrogen, aryl, allyl, or unsubstituted or substituted, linear or branched alkyl having 1-4 carbon atoms(wherein the substituent is a fluorine), R3 is independently chlorine, acetoxy, hydroxy, or unsubstituted or substituted, linear or branched alkoxy having 1-4 carbon atoms(wherein the substituent is a fluorine), each of R4 and R6 is independently hydrogen, allyl, or unsubstituted or substituted, linear or branched alkyl having 1-4 carbon atoms(wherein the substituent is a fluorine), each of R5 and R7 is independently chlorine, acetoxy, hydroxy, or linear or branched alkoxy having 1-4 carbon atoms, n is an integer of 2-20, p is an integer of 0-3, M is linear or branched alkylene, or allylene having 1-6 carbon atoms, each of q and r is an integer of 0-2.
