A heat-generating plate that generates heat when a voltage is applied, including a pair of glasses, a pair of bus bars to which the voltage is applied, and a heat-generating conductor that can couple between the pair of bus bars. The heat-generating conductor includes a plurality of conductive thin wires that linearly extends between the pair of bus bars and couples between the pair of bus bars. An average Wof a width W of one of said conductive thin wires is within a range of the following formula(a) relative to a standard deviation σ of distribution of the width W: 0≤4σ/W≤0.3 (Formula(a)).

In order to improve the scratch resistance of an antireflective article having a moth-eye structure, an antireflective article is provided that has fine protrusions densely arranged therein, and has the interval between adjacent fine protrusions being no more than the shortest wavelength in the wavelength band for antireflection. At least some of the fine protrusions are fine protrusions having a plurality of apexes.

An optical sheet having both of an excellent light condensing function and an excellent scratch resistance is provided. An optical sheet includes: a sheet-like main body; at least three or more first unit shaped elements arranged on one surface of the main body; and second unit shaped elements arranged on the one surface of the main body. Each of the second unit shaped elements extend in parallel with in one direction on a sheet surface of the main body. A height Hof each of the first unit shaped elements from the one surface is higher than a height Hof each of the second unit shaped elements. A rate of an area occupied by the first unit shaped elements on the one surface is not more than 10.0%, when observed along a normal direction nd relative to the one surface.
