    摘要： An electromagnetic wave shielding filter 10 includes a meshed layer, wherein at least one of the front and back surfaces of the meshed layer is subjected to a blackening treatment to be a blackened face having micro-irregularities. The shape of the micro-irregularities is adjusted to have a probability density curve with a peak point being convex upward wherein the probability density curve is defined as a curve depicted in a graph in which the change of height from the peak value Rp to the bottom value Rv of the deepest valley is shown as the horizontal axis while the probability density expressing the distribution of height is shown as the vertical axis. Also, in the probability density curve, a horizontal tangent can be drawn at its peak point.

    摘要： An object of the present invention is to eliminate drawbacks of conventional multi-layered antireflection films, that is, that a lot of time is required in the formation of a transparent conductive thin film and a low-refractive index layer leading to low processing speed, the corrosion resistance of the transparent conductive thin film is unsatisfactory, and the reflectance over the whole visible light region is not constant. This object can be attained by adopting a structure comprising: a transparent layer 3, with a pencil hardness of H or more, formed of a cured product of an ionizing radiation-curable resin composition; provided on one side of the transparent layer 3, a concave-convex portion 2 comprising innumerable fine concaves and convexes provided at a pitch of not more than the wavelength of light; a transparent substrate film 1 optionally provided on the transparent layer 3 on its side remote from the concave-convex portion 2; and a cover layer, having a lower refractive index than the transparent layer, preferably provided on the fine concaves and convexes.

    摘要： An electromagnetic wave shielding filter comprises a transparent substrate 11, and a metal mesh layer 21 with line parts 107 that define openings 105 of the mesh, laminated to one surface of the transparent substrate 11 by an adhesive 13. A first blackening layer 25A and an anticorrosive layer 23A are successively formed on the surfaces, on the transparent substrate side, of the line parts 107 of the metal mesh layer 21. A second blackening layer 25B is formed on surfaces, on the side opposite to the transparent substrate 11, of the line parts 107 of the metal mesh layer 21, and also on side faces of the line parts 107.
