PROBLEM TO BE SOLVED: To provide a method for manufacturing a light-emitting device capable of controlling angle dependence of chromaticity in a wide range.SOLUTION: As an embodiment of the present invention, there is provided a method for manufacturing a light-emitting device comprising the steps of: sealing a light-emitting element 10 by a sealing material 11 including a phosphor 12; and hardening the sealing material 11 by thermal treatment. The method sets a sedimentation degree of the phosphor 12 in the sealing member 11 according to light distribution of the light-emitting element 10.SELECTED DRAWING: Figure 4 【課題】広い範囲で色度の角度依存性を制御することのできる発光装置の製造方法を提供する。【解決手段】本発明の一態様として、蛍光体１２を含む封止材１１により、発光素子１０を封止する工程と、加熱処理により、封止材１１を硬化させる工程と、を含み、発光素子１０の配光分布に応じて、封止材１１中の蛍光体１２の沈降度合いを設定する、発光装置の製造方法を提供する。【選択図】図４
