Translucent structure, method for manufacturing same, and article

A translucent structure comprising a translucent substrate and an antireflection layer provided on a visible side of the translucent substrate so that reflectivity of the translucent structure based on an SCI method is 3% or less,

• wherein a visible-side outermost surface of the translucent structure includes a concave and convex structure as follows:
• the concave and convex structure includes a first convex portion and a second convex portion, the first convex portion having a diameter exceeding 10 μm in a section at a height of 0.05 μm from a bearing height in a surface shape obtained by measuring a region of (101 μm×135 μm) to (111 μm×148 μm) by a laser microscope, and the second convex portion having a diameter exceeding 1 μm in a section at a height of 0.5 μm from the bearing height in the surface shape;
• an average diameter of the first convex portion in the section at the height of 0.05 μm from the bearing height in the surface shape is more than 10 μm and 185 μm or less;
• a maximum height of the first convex portion with reference to a height of a lowest part within the region is 0.2 to 8 μm;
• and
• the number density of the second convex portion is 0.0001 to 1.2 per 1 μm2, and an average height of the second convex portion is 0.1 to 8 μm based on the bearing height,
• wherein the diameter of the first convex portion in a cross section is a diameter of an exact circle which has the same area as the first convex portion in the cross section, and the diameter of the second convex portion in a cross section is a diameter of an exact circle which has the same area as the second convex portion in the cross section.
