Abstract
A phosphor plate includes a plate-like composite including a base material and a phosphor contained in the base material, in which the base material contains spinel, the phosphor includes a phosphor containing a Si element, and in an X-ray diffraction pattern of the phosphor plate using a Cu-Kα ray, in a case in which peak intensity corresponding to the spinel having a diffraction angle 2θ in a range of 36.0° or more and 37.4° or less is set to 1, total intensity of peaks having a diffraction angle 2θ in a range of 32.5° or more and 34.5° or less satisfies 0.5 or less.

A phosphor plate comprising:
- a plate-like composite including a base material and a phosphor contained in the base material,
- wherein the base material contains spinel,
- the phosphor includes a phosphor containing a Si element, and
- in an X-ray diffraction pattern of the phosphor plate measured using a Cu-Kα ray, in a case in which peak intensity corresponding to the spinel having a diffraction angle 2θ in a range of 36.0° or more and 37.4° or less is set to 1, total intensity of peaks having a diffraction angle 2θ in a range of 32.5° or more and 34.5° or less satisfies 0.5 or less.
