The present invention is a structure having a substrate and a fine concavo-convex structure layer provided on at least one surface of the substrate, the fine concavo-convex structure layer is disposed on the surface of the structure, The indentation elastic modulus of the structure is 1 to 1300 MPa, and the ratio (Δμ) of the rate of change of the dynamic friction coefficient of the surface of the structure represented by the following formula (1) is 0.15 to 1.05. It relates to a certain structure. ADVANTAGE OF THE INVENTION According to this invention, without impairing optical performance, such as antireflection performance, the structure excellent in abrasion resistance, its manufacturing method, and an article provided with the said structure can be provided. Δμ = Δμf / Δμs (1) (In Expression (1), Δμs represents the rate of change of the dynamic friction coefficient in the initial wear stage in the reciprocating wear test on the structure surface, and Δμf represents the change in the dynamic friction coefficient immediately before the end of the test in the reciprocating wear test on the structure surface. Represents the rate.) |
