PROBLEM TO BE SOLVED: To provide an antifouling structure of a porous material and a forming method therefor, which combine internal water repellency with surface hydrophilicity, and an antifouling coating agent suitable for the formation of the antifouling structure. SOLUTION: The antifouling structure of the porous material constitutes a one-component coat structure which is coated with a one-component coating agent including a water absorption preventing agent and a photocatalyst. The antifouling structure is composed of a film part which is formed on the surface of the porous material, and a permeation part which permeates into the porous material. The film part has the surface hydrophilicity caused by the photocatalyst, and the permeation part has the internal water repellency caused by the water absorption preventing agent remaining inside the porous material.
