Abstract:
Provided is a method of manufacturing a light emitting device, comprising: preparing a base body having a concave portion; disposing a light emitting element at the bottom of the concave portion; disposing a first resin containing first phosphor particles having an average particle size of 10 μm or more and 30 μm or less and a first filler having an average particle size of 5 μm or more and 20 μm or less to cover the light emitting element; centrifugally precipitating the first phosphor particles and the first filler toward the base body; temporarily curing the first resin; disposing a second resin containing second phosphor particles and a second filler having an average particle size of 5 nm or more and 100 nm or less on the first resin temporarily cured; centrifugally precipitating the second phosphor particles and the second filler toward the first resin; and curing the first and second resins.
