Provided is an antifouling coating composition capable of exhibiting an antifouling effect for a long period of time even in ocean water containing highly active barnacles, serpula, and other animal species, as well as hydrozoans and other coelenterates. This antifouling coating composition comprises (A) copper glass containing divalent copper, (B) metal pyrithiones, and (C) titanium oxide, wherein the metal of the metal pyrithiones is copper or zinc; the composition further contains a spreading resin; the content of copper in the copper glass (A) is 24—40 mol%; the content of the copper glass (A), in terms of solid content, is 1—20 mass% of the solid content of the antifouling coating composition; the content of the metal pyrithiones (B), in terms of solid content, is 25—150 parts by mass per 100 parts by mass of the copper glass (A); and the content of the titanium oxide (C), in terms of solid content, is 50—300 parts by mass per 100 parts by mass of the copper glass (A). |
