A wavelength conversion member that includes a single crystal phosphor and has a high yield rate is provided. A light emitting unit (1) is a wavelength conversion member that converts a wavelength of a laser light output from a laser light source and includes a phosphor layer (1a) formed of a single crystal phosphor. A plane orientation of a principal plane (1b), which has an area larger than those of divided planes, of the phosphor layer is {111}, and a plane orientation of some divided planes out of the plurality of divided planes is {1-10}.
