Abstract

A transparent electroconductive film with a protective film includes: a transparent electroconductive film including a film substrate, an optical adjustment layer formed on one main surface of the film substrate, and a transparent conductive layer formed on the optical adjustment layer; and a protective film bonded to a main surface of the film substrate on a side opposite to the transparent conductive layer, wherein the transparent electroconductive film and the protective film are thermally shrinkable in at least one direction in a main surface, and the absolute value of the maximum thermal shrinkage ratio (%) of the transparent electroconductive film in a main surface is smaller than the absolute value of the maximum thermal shrinkage ratio (%) of the protective film in a main surface, and the difference between the absolute values is 0.05% to 0.6%.
