An organic electroluminescence device is provided which is capable of providing light emission lasting time that can be practically used, that is, of improving its light emission life. A light emitting body used in the organic electroluminescence device is made up of a lower electrode layer, a light emitting layer and a transparent electrode layer being stacked in order on a substrate. As a material for the transparent electrode layer, a substance "In2-xSnxO3-y" being a mixture of an oxide of indium with tin is employed as its chief component. A material having hygroscopicity is formed adjacent to the transparent electrode layer. Light emitting element portion made up of the electrode and light emitting material layer is the electroluminescence device.
