Abstract: A substrate having a transparent conductive layer has a transparent conductive pattern that is not easily visually recognizable by a naked human eye on a transparent substrate and can be formed by a simple and efficient method. In the case where a transparent conductive pattern is formed on a transparent substrate, the pattern region does not include conductive regions covered with uniform transparent conductive films or a high-resistance region that is not covered with the transparent conductive film, the high-resistance region electrically insulating the conductive regions. Instead of the conductive regions or the high-resistance region, the inventors use a region having a structure including a mixture of a portion covered with the transparent conductive film and a portion not covered with the transparent conductive film, thereby solving the foregoing visual recognition issue.
