Abstract
A light-emitting device includes: a light-emitting element; a light-transmissive member that covers the light-emitting element; and a light-diffusing particles contained in the light-transmissive member. The light-diffusing particles are hollow and have a particle size not smaller than 50 μm. The light-transmissive member has a surface having irregularities associated with the light-diffusing particles. A method for manufacturing a light-emitting device includes steps of: mounting a light-emitting element in a recess of a base member; injecting a silicone resin containing light-diffusing particles into the recess, the light-diffusing particles having a particle size not smaller than 50 μm; causing the light-diffusing particles to float up to a surface of the injected silicone resin; and curing the injected silicone resin.
