This composite phosphor (1) is configured from two or more types of phosphor particles with at least different diameters, wherein multiple second phosphor particles (3) adhere on the surface of first phosphor particles (2), and the first phosphor particles (2) are larger than the second phosphor particles (3). By mixing these composite phosphors (1) in a resin (13), the ratio of the first phosphor particles (2) and the second phosphor particles (3) does not change even over time, thus effecting that the chromaticity coordinates of the light emitting device when mounted are not prone to shift.
