A light emitting apparatus includes a light emitting device emitting primary light and a wavelength conversion unit absorbing a part of the primary light to emit secondary light. The wavelength conversion unit includes a first wavelength conversion unit containing at least a nanocrystalline phosphor and a second wavelength conversion unit containing a rare-earth-activated phosphor or a transition-metal-element-activated phosphor. In the light emitting device, the first wavelength conversion unit and the second wavelength conversion unit are closely stacked in order.
