Abstract
Provided are: a transparent electroconductive film with good transparency, wherein the transparent electroconductive film has antiblocking properties that can withstand roll-to-roll manufacturing, and white haze on the transparent electroconductive film side is reduced. Also provided is a touch sensor in which the transparent electroconductive film is used. This transparent electroconductive film includes a transparent substrateand a transparent electroconductive filmformed on one side of the transparent substrate, wherein the arithmetic mean surface roughness Ra in a 452×595 μm field of view on the surface of the transparent electroconductive filmis greater than 0 nm and no more than 10 nm, and the arithmetic mean surface roughness Ra in a 452×595 μm field of view on the surface of the transparent substrateon which the transparent electroconductive filmis not formed is greater than 5 nm and less than 100 nm.
