Beschreibung
Zusammenfassung:	The present invention relates to a phosphor plate including a sintered body including (Y1-x-y, Gdx, Cey)3Al5O12 particles and Al2O3 particles, in which 0.07≤x≤0.11 and 0.010≤y≤0.015 are satisfied, the (Y1-x-y, Gdx, Cey)3Al5O12 particles in the sintered body has an average particle diameter of 4 μm or more and 6 μm or less, the (Y1-x-y, Gdx, Cey)3Al5O12 particles has a concentration of 20 vol % or more and 30 vol % or less with respect to a total amount 100 vol % of the (Y1-x-y, Gdx, Cey)3Al5O12 particles and the Al2O3 particles, a ratio of an average particle diameter of the Al2O3 particles to the average particle diameter of the (Y1-x-y, Gdx, Cey)3Al5O12 particles is 1 or more and 2 or less, and the sintered body has a total thickness of 150 μm or more and 250 μm or less.
