A nitrogen-containing layer, a conductive layer mainly composed of silver provided adjacent to the nitrogen-containing layer, a high-refractive index layer having a higher refractive index than the nitrogen-containing layer, and a refractive index higher than that of the high-refractive index layer A transparent electrode having a low low refractive index layer is formed. The nitrogen-containing layer contains a nitrogen atom and the number of unshared electron pairs that are not involved in aromaticity and not coordinated to the metal among the unshared electron pairs that the nitrogen atom has is n, and the molecular weight is M In this case, a compound having an effective unshared electron pair content [n / M] of 2.0 × 10 −3 ≦ [n / M] is used. |
