Abstract

A highly reliable light emitting apparatus which emits light with high efficiency is obtained. The light emitting apparatus includes a light emitting member, a refrigerant, and a housing. The light emitting member includes a first surface including a phosphor irradiated with light to emit light, and a second surface different from the first surface. The refrigerant cools the light emitting member. The housing includes a holding portion for holding the refrigerant. A surface of the housing is provided with an opening communicating with the holding portion. The light emitting member is connected to the housing such that the second surface closes the opening.
