Abstract:
A conductive film includes a wiring pattern having the following characteristics. For each spectrum in which spectrum peaks obtained by performing two-dimensional Fourier transform on transmittance image data of the entire image has normalized spectrum intensities equal to or greater than a specified value, an angle is set to oscillate by each unit of a specific angle. Intensity differences, each of which is obtained from a maximum value and a minimum value of the normalized spectrum intensity for each angle, are calculated. One or more clusters of bars, which indicate frequencies of a histogram at an average value or more of the intensity difference in a case where the histogram is a histogram of the intensity differences, are isolated from the other cluster. In addition, in a case where a second sample standard deviation indicating a variation of first sample standard deviations, each of which indicates a variation of the normalized spectrum intensities at a single angle, in all angular directions is calculated as a quantitative value of the wiring pattern, the quantitative value is in a specific numerical value range.
