Abstract:
A light emitting device includes a first light emitting element having a top face and a bottom face which faces the base, and a second light emitting element. A wavelength conversion member is provided on the top face and includes a light transmitting part made of an inorganic material and a phosphor layer. The light transmitting part has an upper face and a lower face. A phosphor layer is disposed between the lower face and the top face. The phosphor layer is bonded to the top face of the first light emitting element. The reflecting member covers the lateral faces of the phosphor layer. A light transmissive sealing resin is disposed on the base between the first and second light emitting elements and between the wavelength conversion member and the second light emitting element. The light transmissive sealing resin covers the lateral faces via the reflecting member.
