Abstract
Provided is a transparent electroconductive laminate which can prevent the occurrence of Newton rings between two transparent electrode substrates constituting a transparent touch panel. Also provided is a transparent touch panel which comprises the transparent electroconductive laminate. A transparent electroconductive laminate (14, 15, 16) comprises a transparent organic polymer substrate (16), and comprises an uneven-surfaced hardened resin layer (15) and a transparent electroconductive layer (14) which are successively laminated on at least one side of the transparent organic polymer substrate. The transparent electroconductive laminate is characterized in that the hardened resin layer comprises a hardening resin component and at least one of ultrafine metal oxide particles (A) and ultrafine metal fluoride particles (B), these particles having an average primary particle diameter of 100 nm or less and being dispersed in the hardening resin component. The contents of the ultrafine particles (A) and (B) in the hardened resin layer are each 1 part by mass or more to less than 20 parts by mass per 100 parts by mass of the hardening resin component. The ratio by mass (A/B) of the ul…
