Abstract:
A method of manufacturing a light-emitting device 1 includes a step of providing first phosphor sheets 11, a step of providing second phosphor sheets 12, a step of providing a light-emitting element 13, a selection step of selecting a combination of one of the first phosphor sheets 11 and one of the second phosphor sheets 12 on the basis of a wavelength conversion characteristic of each of the first phosphor sheets 11 and a wavelength conversion characteristic of each of the second phosphor sheets 12, a step of obtaining a plurality of first phosphor pieces 11c and a plurality of second phosphor pieces 12c from the selected first phosphor sheet 11 and the selected second phosphor sheet 12, and a step of disposing one of the first phosphor pieces 11c and one of the second phosphor pieces 12c on or above the light-emitting element 13.
