Provided is a curable resin composition which exhibits excellent curability and is good in storage stability. The curable resin composition comprises (a) a polymer having a hydrolyzable silyl group, (b) an acid catalyst, and (c) an onium salt represented by the following general formula (1):n nC + A − (1)n wherein C + is an onium cation, and A − is a hydrogen sulfate anion, a hydrogen sulfite anion, a sulfonate anion represented by R 1 SO 3 − wherein R 1 represents an alkyl group, perfluoroalkyl group, cycloalkyl group, vinyl group, aryl group, perfluoroaryl group, aralkyl group or halogen atom; or a bis(substituted sulfonyl)imide anion represented by (R 2 SO 2 ) 2 N − wherein R 2 represents an alkyl group, perfluoroalkyl group, or aryl group; tetrafluoroborate anion, or hexafluorophosphate anion. |
