Abstract
A phosphor particle is configured to emit fluorescence longer in wavelength than excitation light entering the phosphor particle. The phosphor includes a concave portion which is no smaller than 0.1 times as large as the wavelength of the fluorescence and no larger than 10 times as large as the wavelength of the fluorescence. The concave portion is disposed on a surface of the phosphor particle.
