A solid-state light source device is equipped with a semiconductor light emitting element and a wavelength conversion element. The semiconductor light emitting element has a first light emitter and a second light emitter. The wavelength conversion element has a first wavelength converter containing a first phosphor and has a second wavelength converter containing a second phosphor. The first wavelength converter and the second wavelength converter are disposed apart from each other. The first light emitter emits first excitation light, and the second light emitter emits second excitation light. The first phosphor converts the first excitation light into first-wavelength light, and the second phosphor converts the second excitation light into second-wavelength light.
