(57) Abstract: A coating liquid for forming a porous organic film capable of lowering the dielectric constant as an insulating material used for an electronic component, and a method for forming a porous organic film are provided. SOLUTION: The following A) to C) are contained as essential components, and the respective thermal decomposition onset temperatures Ta and Tb of A) and B) are included. A coating liquid for forming a porous organic film, wherein Ta> Tb, and a method for forming a porous organic film using the coating liquid. A) a thermosetting resin having an aromatic ring in its main chain; B) a thermodegradable resin obtained by polymerizing monomers containing a compound represented by the following formula (1) or (2); C) an organic solvent Or (Wherein X is an alkenyl group having 2 to 6 carbon atoms, R 1 to R 3 independently represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms. And R 1, R 2, R 3 in the formula (1), the R 1, R 2, R 3 in the formula (2) may be different. ) |
