Abstract

in which, in Equations (1) and (2), Y represents the average molecular weight of the antifouling liquid, and X represents a kinematic viscosity (cSt) at 20° C. of the antifouling liquid.

First claim

1 - 4 . (canceled)

5 . An antifouling structure comprising an oxide layer, a surface modification layer that modifies a surface of the oxide layer, and an antifouling liquid retained in the surface modification layer;
wherein the surface modification layer is a modification layer derived from a silane coupling agent; the antifouling liquid includes a first antifouling liquid satisfying Equation (1) below and a second antifouling liquid satisfying Equation (2) below; each of the first antifouling liquid and the second antifouling liquid has a molecular structure that does not include a functional group; and a volume ratio (first antifouling liquid/second antifouling liquid) of the first antifouling liquid to the second antifouling liquid is from 1/2 to 100/1:
Y≤ 3 X+ 2000  Equation (1)

Y> 3 X+ 2000  Equation (2)

in which, in Equations (1) and (2), Y represents an average molecular weight of the antifouling liquid, and X represents a kinematic viscosity (cSt) at 20° C. of the antifouling liquid.

6 . The antifouling structure according to claim 5 , wherein an average molecular weight of the second antifouling liquid is 3000 to 5000.

7 . The antifouling structure according to claim 5 , wherein a kinematic viscosity X1 (cSt) at 20° C. of the first antifouling liquid and a kinematic viscosity X2 (cSt) at 20° C. of the second antifouling liquid satisfy a relationship in Equation (3) below:
X 1> X 2  Equation (3)

8 . The antifouling structure according to claim 5 , wherein the oxide layer has a surface including unevenness.
