Zusammenfassung:A surface modification method for modifying a surface of an oxide includes: producing a surface modification composition; and applying the surface modification composition onto the surface of an oxide layer. In producing the surface modification composition, a modifier having a perfluoropolyether chain is mixed with a first modification accelerator containing an inorganic acid and a second modification accelerator containing at least one selected from the group consisting of a metal, a metal salt and an organometallic compound. A surface modification composition, concurrently comprising: a modifier having a perfluoropolyether chain; a first modification accelerator containing an inorganic acid; and a second modification accelerator containing at least one selected from the group consisting of a metal, a metal salt and an organometallic compound. A surface modification composition set, comprising: a modifier having a perfluoropolyether chain; a first modification accelerator containing an inorganic acid; and a second modification accelerator containing at least one selected from the group consisting of a metal, a metal salt and an organometallic compound. An antifouling structure precursor, comprising: a modification layer that contains a modifier having a perfluoropolyether chain; and an oxide layer that has a surface entirely covered with the modification layer, wherein the modification layer has an uneven film thickness and comprises a comparatively thick area and a comparatively thin area that is dispersed in the comparatively thick area, and a coverage rate of covering the oxide layer with the comparatively thick area is equal to or greater than 10%. An antifouling structure, comprising: an antifouling structure precursor; and a lubricant oil on a surface of the antifouling structure precursor.
