  Provided are an antifouling coating composition that contains: a hydrolyzable resin having a specific silicon-containing group and a metal-atom-containing group containing a divalent metal atom M; and a thermoplastic resin and/or a plasticizer, wherein the total content of the thermoplastic resin and/or plasticizer per 100 parts by mass of the hydrolyzable resin is 3 to 100 parts by mass, an antifouling film, a composite film and an in-water structure such as a ship using the antifouling coating composition. The antifouling coating composition makes it possible to form a coating film that is excellent in crack resistance and exhibits a good antifouling property over a long period of time even when no antifouling agent is contained or the blending amount thereof is small.
