A light-emitting device includes: a set of layers including (i) a light-transmissive member having a top surface, a bottom surface, and a lateral surface contiguous with the top surface and the bottom surface, (ii) a first phosphor layer disposed below the bottom surface, and (iii) a dielectric multilayer film between the light-transmissive member and the first phosphor layer; a cover layer disposed on a lateral surface of the set of layers; and a light-emitting element disposed below the first phosphor layer. The light-emitting element emits blue light. The first phosphor layer absorbs at least a portion of the blue light and emits yellow-red to red light. The cover layer is either: a second phosphor layer that absorbs at least a portion of the blue light emitted by the light-emitting element and emits yellow-red to red light, or a pigment layer that presents yellow-red to red light.
