Electromagnetic wave shielding filter |
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.
