摘要

PROBLEM TO BE SOLVED: To provide a water-repelling and oil-repelling antifouling glass which has improved durability such as wear resistance and weatherability, water droplet repellency, oil repellency, and antifouling performance in addition to water-repelling and oil-repelling functions, a method for manufacturing the same, and a glass window using the same, a solar energy utilization device, and optical equipment.SOLUTION: A wear-resistant, water-ultrarepellent and oil-repellent antifouling glass 10 has a glass substrate 14 having a plurality of confetti-like projections 11 and a water-repellent, oil-repellent and antifouling thin film 15a bonded to at least one part of the surface of the glass substrate 14 having a confetti-like projection 11, and the confetti-like projection 11 is composed of a substantially hemispherical first projection 12 and a plurality of conically-shaped or bamboo shoot shaped second projection 13 which are formed on the surface of the first projection 12 and have a smaller diameter of the bottom face than the first projection 12.
