Rare earth phosphate particles of the present invention comprises aggregated particles formed of a plurality of primary particles of a rare earth phosphate represented by LnPO, wherein Ln represents at least one element selected from the group consisting of Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb, and Lu. The cumulative volume particle size at a cumulative volume of 50 vol%, D, of the aggregated particles is from 0.1 µm to 20 µm as measured through particle size distribution analysis using a laser diffraction and scattering method. The rare earth phosphate particles of the present invention are to be distributed in a substrate or on a surface of a substrate and used to cause scattering of light.
