Abstract
The conductive sheet according to the present invention includes a base and a conductive portion that is formed on at least one main surface of the base and is formed from a plurality of thin metal wires, where a mesh pattern in which different mesh shapes are arrayed in plan view is formed by the conductive portion, and the mesh pattern is configured such that, in a power spectrum of a two-dimensional distribution of centroid positions of the mesh shapes, an average intensity on a higher spatial frequency band side than a predetermined spatial frequency is larger than an average intensity on a lower spatial frequency band side than the predetermined spatial frequency. The conductive sheet can reduce the granular feeling of noise due to pattern which the conductive sheet has and greatly improve the visibility of an object for observation.
