Abstract
A method of manufacturing a fluorescent substance includes forming dicing trenches on one surface of a fluorescent substance wafer along lattice-shaped dicing lines, and a lower surface grinding operation (S) of grinding a surface opposite to a surface of the wafer in which the dicing trenches are formed as much as a predetermined thickness using a disk-shaped grinder so that the wafer is divided into a plurality of fluorescent substances, which are color conversion members for light emitting diodes (LEDs).
