To provide an electrode for an organic device which can realize a hole injection function and/or an electron injection function from a totally different point of view from metal donor doping. A composite material in which conductive particles of a particulate conductive inorganic compound (the diameter is 1 (nm) to 100 (nm), preferably, 1 (nm) to 20 (nm)) are dispersed in one or plural kinds of organic compounds 101 is layered on a surface of an organic layer 110 of an organic device where an electrode is to be formed to form an electrode for an organic device 100. As to the thus formed electrode, since the densely dispersed conductive particles 102 have large specific surface area, interaction between the conductive particles 102 and the organic compound 101 realizes a function of a donor or an acceptor. Besides, since adhesion with the organic layer 110 is high for the existence of the matrix of the organic compound 101, the electrode is suitable for an organic device.
