Abstract
An anti-fouling coating film of the present invention includes a component (A): zirconium; a component (B): lanthanum; and a component (C): at least one selected from the group consisting of silicon, phosphorus, and boron, in which in a case where masses of the component (A), the component (B), and the component (C) are used by being converted into masses of oxides thereof, total mass of the component (A) and the component (B) with respect to a mass of the anti-fouling coating film is 90% or more and 95% or less, and in a case where X is defined by X=mass of component (B)/(total mass of component (A)+component (B))×100, X is 20% or more and 50% or less, and the mass of the component (C) to the mass of the anti-fouling coating film is 5% or more and [6+(X−20)/6]% or less.
