Claim 9:
10. The white light emitting device according to claim 8,
wherein the first phosphor members include phosphor particles and the second phosphor members include phosphor particles,
when VP1 is an average value of volumes of all of the first phosphor members included in the first light-emitting unit group, and D1 is an average value of volume concentrations of the phosphor particles of all of the first phosphor members included in the first light-emitting unit group, and
VP2 is an average value of volumes of all of the second phosphor members included in the second light-emitting unit group, and D2 is an average value of volume concentrations of the phosphor particles of all of the second phosphor members included in the second light-emitting unit group,
relations of 0.954≤VP2/VP1≤0.976 and D1=D2 are satisfied.
