35. A method for producing an antifouling structure that comprises:
- a base;
a structure that is formed on a surface of the base and comprises a microporous structure with micropores; and
a fluorine-containing liquid retained in the micropores of the microporous structure, wherein elemental fluorine is present in a surface of the microporous structure, and an average diameter of surface openings of the micropores in the microporous structure is equal to or greater than 10 nm,the method comprising; forming the structure on the surface of the base, in which the structure comprises the microporous structure with the micropores having an average diameter of the surface openings of 10 nm or more, and the elemental fluorine is present in the surface of the microporous structure, wherein the forming step comprises;
applying an application liquid containing a polymerizable organometallic compound, an organometallic compound having a fluorine functional group and an acid or basic catalyst to the base;
then heating the base at 20°
