Abstract: A phosphor according to the present disclosure has excellent light emission properties in a blue-green region and high color rendering properties. The phosphor is represented by a chemical formula of Lu(3-x-y-z)MgxZnyAl5O12:Cez, in which when z is in a range of 0.01≤z≤0.03, then 0≤x≤1.4 and 0≤y≤1.4, excluding x=0 and y=0; when z is in a range of is 0.03
