Abstract
A method for manufacturing a light emitting device having a light emitting element and a resin layer containing fluorescent material particles and a filler which reflects light comprises a fluorescent material precipitation process for precipitating the fluorescent material particles in advance of the filler. A light emitting device comprises a base body; a light emitting element mounted on an upper surface of the base body via a mounting portion; and a sealing resin for sealing the light emitting element. The sealing resin comprises: a fluorescent material-containing first layer for covering the light emitting element on and above the mounting portion, a fluorescent material-containing second layer formed on an upper surface of the base body around the mounting portion, and a filler-containing layer formed on the fluorescent material-containing second layer around the mounting portion.
