A product includes a first area and a second area. Each area includes areas having a first optical property and areas having a second optical property. The areas having the first optical property and the areas having the second optical property are arranged under a specific rule. In the first area, convex portions whose height is equal to or smaller than a predetermined height or no convex portions are formed. In the second area, convex portions whose height is larger than the predetermined height are formed.

Product and method of manufacturing product

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 molding has a first surface and a second surface, wherein the second surface includes a rib, and wherein the first surface includes a glossy portion and a non-glossy portion.

Resin molding, printer, and method for manufacturing resin molding

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.

Resin product, method of making resin product, interchangeable lens, and optical device

A resin product includes an outer surface. The outer surface includes a first area and a second area. The first area includes a surface pattern including a concave and convex portion having a first difference in height. The second area includes a surface pattern including a concave and convex portion having a second difference in height, larger than the first difference in height. An arithmetic average height of a top of a convex portion of the concave and convex portion having the first difference in height is larger than an arithmetic average height of a top of a convex portion of the concave and convex portion having the second difference in height.

Resin product, electronic device, and method of making resin product

There is provided a resin molded product including a hairline pattern having small roughness and high gloss. The resin molded product includes a surface having a hairline pattern in which a plurality of ridges extending in an X direction is arranged in a Y direction, thus the plurality of ridges includes a plurality of first ridges and a plurality of second ridges higher than the first ridges, with the hairline pattern having a maximum height Ry of 6 [&#x3bc;m] or less in the X direction, and an arithmetic average curvature Spc of apex points of 625 [1/mm] or less.

Resin molded product, electronic device, mold, method for manufacturing mold and method for manufacturing resin molded product

A filler-containing resin molded product with a surface which includes irregularities which are transferred from a mold cavity to the surface and have an arithmetic mean roughness of 0.8 &#x3bc;m or greater and 10 &#x3bc;m or less and a peak arithmetic mean curvature of 400 [1/mm] or greater and 900 [1/mm] or less.
