    Abstract: A resin product wherein a resin B has pillar structures or lamellar structures inside a resin A is molded by kneading the resin A and the resin B that serves as a base material in an injection molding machine while heating both of the resins to at least a temperature at which both of the resins are melted at least partially. The resin product is soaked in a solution having higher erosion capability with respect to the resin A than the resin B, thereby dissolving the resin B and forming an uneven structure on the surface. As a result, an uneven structure having various shapes, densities or depths which are precisely adjustable can be formed at low cost. And provided are a resin structure and a production method thereof that can maintain wettability control or optical property control of the molded article over a long period of time.

    Abstract translation: 树脂A中的树脂B具有支柱结构或层状结构的树脂制品通过在注塑机中捏合树脂A和用作基材的树脂B来模塑，同时将两种树脂加热至至少温度 其中两种树脂至少部分地熔融。 将树脂产品浸泡在树脂A中比树脂B具有较高腐蚀能力的溶液中，从而溶解树脂B并在表面上形成不均匀的结构。 结果，可以以低成本形成具有精确可调节的各种形状，密度或深度的不均匀结构。 并且提供了能够长时间保持模制品的润湿性控制或光学性质控制的树脂结构及其制造方法。

    Abstract: A wire-grid polarizer includes metal reflectors which are embedded in a large number of grooves formed in a one-dimensional grid pattern in the same direction and with the same period in the front surface of a transparent sheet, wherein the average width (a) of the metal reflectors is 200 nm or less, the ratio (b/a) of the average thickness (b) of the metal reflectors from the front side of the sheet to the tip in the backward direction to the above average width (a) is 4 to 25, in any cross-section perpendicular to the surface of the sheet, the shape of each of the metal reflectors in the vicinity of the tip in the thickness direction is such that it gradually becomes thinner in a linear or smoothly curved shape toward the tip, and the ratio of the average length (c) toward the tip of portions that gradually become thinner toward the tip to the above average width (a) is 1.2 or more.
