1. A transparent electrode comprising:
a patterned electrode layer formed on a transparent substrate, provided that said electrode layer has an electroconductive film containing metal nanowires and also has a protective film containing N-graphene in which carbon atoms in the graphene carbon skeleton are partly substituted with nitrogen atoms and are connected with polyethylene-imine chains, wherein
said protective film is lying on said electroconductive film and an upper part of the electroconductive film is covered with said N-graphene.
