PROBLEM TO BE SOLVED: To provide a method of manufacturing an LED light-emitting device that has an LED element sealed with a sealing resin containing a phosphor, the LED light-emitting device having small variance in chromaticity and high reliability in quality.SOLUTION: A method of manufacturing an LED light-emitting device 100 includes steps as follows: (1) a sealing step of sealing an LED element with a phosphor-containing curable resin before curing processing; (2) a temporary curing step of curing the phosphor-containing resin into a temporary curing state, in which at least some of phosphor particles that the phosphor-containing resin contains precipitate in the phosphor-containing resin, before a curing state as an in-use state of the LED light-emitting device 100; (3) a precipitating step of causing at least some of phosphor particles to precipitate toward a surface of the phosphor-containing resin in contact with air; and (4) a primary curing step of curing the phosphor-containing resin in the temporary curing state in which at least some of the phosphor particles precipitate into the curing state as the in-use state of the LED light-emitting device 100. |
