A light scattering sheet (light scattering body) according to the present invention is constituted of a molded resin body in which light scattering particles are distributed in a resin. The light scattering particles are particles of a phosphate of a rare earth element. The surface area of the light scattering particles per unit volume of the molded resin body is not greater than 0.600 m2/cm3. Preferably, the cumulative-volume particle diameter D50 of the light scattering particles with a cumulative volume of 50 vol%, obtained by using the laser diffraction/scattering particle-size-distribution measurement method, is 0.1-20 μm. Also preferably, the value of D99/D50, which is the ratio of D99 to D50 of the light scattering particles, where D99 signifies the cumulative-volume particle diameter with a cumulative volume of 99 vol%, obtained by using the laser diffraction/scattering particle-size-distribution measurement method, is not greater than 10.
