Abstract
A method of manufacturing a light emitting device includes injecting liquid or pasty transparent resin into a sheet forming mold, adding a phosphor to the resin in the mold, centrifugally rotating the mold so as to settle the phosphor included in the resin toward one surface side of the resin, thermally curing the resin so as to form a phosphor sheet, the phosphor sheet including a phosphor layer formed on the one surface side of the resin and a transparent layer formed on an other surface side of the resin, overlaying the phosphor sheet on a light emitting element such that the phosphor layer of the phosphor sheet contacts with a light emitting surface of the light emitting element, mounting the light emitting element with the phosphor sheet overlaid on a board, and flattening a surface of the transparent layer of the phosphor sheet on the light emitting element.
