This anti-fouling coating film contains: component (A), zirconium; component (B), lanthanum; and component (C), at least one selected from the group consisting of silicon, phosphorus, and boron. If the total masse of component (A), component (B) and component (C) is calculated in terms of oxides, the total mass of component (A) and component (B) is 90% - 95% relative to the mass of the anti-fouling coating film. If the value of mass of component (B)/(total mass of component (A) + component (B)) × 100 is denoted by X, the value of X is 20% - 50%. The mass of the component (C) relative to the mass of the anti-fouling coating film is not less than 5% and not more than [6 + (X - 20)/6]% or less.
