A product includes a fine periodic structure having a plurality of projection portions extending parallel to each other in a first direction in each of a first region and a second region adjacent in the first direction on a surface of a substrate. The fine periodic structure formed in an inner portion of the first region and the fine periodic structure formed in an inner portion of the second region are substantially the same periodic structures. End portions of the plurality of projection portions formed in the first region and end portions of the plurality of projection portions formed in the second region are formed in a boundary portion between the first region and the second region.

A molded resin product includes a plurality of protrusions formed in a predetermined region. A histogram indicating a height distribution of the plurality of protrusions has two peaks having a boundary height as a boundary therebetween. In a case where protrusions having height equal to or smaller than the height Hx are first protrusions and protrusions having height larger than the boundary height are second protrusions among the plurality of protrusions, an arithmetic mean curvature of the first protrusions is smaller than an arithmetic mean curvature of the second protrusions.

Molded resin product, method for manufacturing molded resin product, mold, and apparatus for manufacturing molded resin product

A resin product including an antireflection surface includes a plurality of first concave portions, a plurality of second concave portions, and a component surface. The first concave portions have opening widths equal to or larger than 1 &#x3bc;m and equal to or smaller than 300 &#x3bc;m. The second concave portions are formed on each of the plurality of first concave portions and have opening widths equal to or larger than 10 nm and equal to or smaller than 1 &#x3bc;m. The component surface is configured to surround each of the plurality of first concave portions.
