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

Abstract: A phosphor has a plate-shaped phosphor, a joining-member, and a light collecting optical member. The light collecting optical member has at least one convex surface and is fixed to the plate-shaped phosphor by the joining-member. The joining-member forms a fillet shape between a surface of the plate-shaped phosphor to which the light collecting optical member is joined and a convex surface of the light collecting optical member. In a case where a height of the fillet shape from the surface of the plate-shaped phosphor to which the light collecting optical member is joined is set as a height X and a maximum distance of the light collecting optical member from the surface of the plate-shaped phosphor to which the light collecting optical member of is joined is set as a maximum distance Y, the height X is equal to or less than ⅔ of the maximum distance Y.
