A light-emitting device has a light-emitting substrate having a circuit pattern layer over one surface of an insulating substrate and a plurality of light-emitting elements bonded to the circuit pattern layer, the light-emitting substrate has a phosphor layer on one surface side of the insulating substrate and includes a phosphor wherein the light emission peak wavelength is in a visible light region when the light emission of at least one of the light-emitting elements is used as excitation light, the elements have a plurality of serial bodies wherein the light-emitting elements are connected in series and arranged in parallel from an inner to an outer side of the substrate surface when the substrate surface of the light-emitting substrate is viewed from a top surface, and anode sides of the serial bodies are arranged on the same side of either the inner or the outer side of the substrate surface.
