A transparent conductive film roll which has a transparent conductive layer on at least one surface thereof and has an excellent distribution uniformity of surface resistance in longitudinal and lateral directions thereof wherein the distribution uniformity D of surface resistance defined by the following expression (1) is 0.2 or less when the surface resistance of the transparent conductive layer is measured at a total of 33 points within the film roll, and therefore, is suitable especially for a large panel,(max&#x2212;min)/(max+min)&#x2003;&#x2003;(1)where Rmax and Rmin represent the maximum and minimum values of 33 surface resistance measurement values.

Transparent conductive film roll and production method thereof, touch panel using the same, and non-contact surface resistance measuring device
