Abstract: A light emitting device is provided. The light emitting device includes a light emitting element, which emits blue light, and a light transmissive member having a first principal face bonded to the light emitting element and a second principal face opposite the first principal face. The light transmissive member has a light transmissive base material and wavelength conversion substances, which are contained in the base material and which absorb the light from the light emitting element and emit light. The wavelength conversion substances are localized in the base material towards the first principal face, and include a first phosphor which emits green to yellow light and a second phosphor which emits red light. The first phosphor is more localized towards the first principal face than the second phosphor. The second phosphor is a manganese-activated fluoride phosphor.
