Provided is a light-emitting device that includes a solid-state light source emitting excitation light and a phosphor layer having a first refractive index, provided on a light-emitting surface side of the solid-state light source, and having a first reflection film on its side surface. The light-emitting device further includes a low refractive layer provided on the phosphor layer and having a second refractive index less than the first refractive index, and a sealing member encapsulating the phosphor layer and the low refractive layer and having a third refractive index greater than or equal to the second refractive index.
