PURPOSE:To provide a high-quality transparent electric conductor having low resistance, high transmissivity, and proper surface irregularities, by forming a transparent conductive film of a transparent electric conductor into multilayer state and providing severally characteristic functions to respective layers. CONSTITUTION:This transparent electric conductor is prepared by forming, on a substrate, a transparent conductive film consisting of plural layers which have practically equal constituents and practically equal reflactive index and are different at least in one property among specific resistivity, light transmissivity, and surface shape. For example, a primary conductive layer 2 consisting of a low-resistance conductive layer with lower resistance value greatly contributing toward the resistance reduction of the transparent conductive film 5 on the substrate 1. On this layer, a secondary conductive layer 3 in which surface is made irregular in order to increase short-circuit density and improve photoelectric transducing ratio at the time of application to an amorphous silicon solar cell, so that transparent conductive film 5 of two-layer system can be formed.
