Abstract
A transparent electroconductive laminate comprising an organic polymer film having stacked on at least one surface thereof an optical interference layer and a transparent electroconductive layer in this order, the optical interference layer comprising a high refractive-index layer and a low refractive-index layer, with the low refractive-index layer being in contact with the transparent electroconductive layer, and the optical interference layer being composed of a crosslinked polymer, wherein the optical interference layer contains ultrafine particles A comprising a metal oxide and/or a metal fluoride and having a primary diameter of 100 nm or less, and/or at least one of the high refractive-index layer and the low refractive-index layer contains fine particles B having an average primary diameter as large as 1.1 times or more the thickness of the optical interference layer and an average primary diameter of 1.2 μm or less in an amount of 0.5 wt % or less of the crosslinked polymer component. This transparent electroconductive laminate is used as a transparent electrode substrate of a transparent touch panel.
