The mixed layer contains an organic compound which contains no nitrogen atoms, i.e., an organic compound which dose not have an arylamine skeleton, and a metal oxide. As the organic compound, an aromatic hydrocarbon having an anthracene skeleton is preferably used. As such an aromatic hydrocarbon, t-BuDNA, DPAnth, DPPA, DNA, DMNA, t-BuDBA, and the like are listed. As the metal oxide, molybdenum oxide, vanadium oxide, ruthenium oxide, rhenium oxide, and the like are preferably used. Further, the mixed layer preferably shows absorbance per 1 μm of 1 or less or does not show a distinct absorption peak in a spectrum of 450 to 650 nm when an absorption spectrum is measured.
