Abstract
A light emitting device manufacturing method includes bonding an electrode of a light emitting element to a conductive member of a base. First wavelength conversion particles, second wavelength conversion particles and filling particles are electrodeposited on a surface of the light emitting element to form a wavelength conversion layer in which the filling particles are disposed among the first wavelength conversion particles and the second wavelength conversion particles. The first wavelength conversion particles contain aluminum. The second wavelength conversion particles have surfaces covered with covering material which contains aluminum. The filling particles contain aluminum. The filling particles have particle size smaller than particle sizes of both the first wavelength conversion particles and the second wavelength conversion particles. The filling particles have aspect ratio smaller than aspect ratios of both the first wavelength conversion particles and the second wavelength conversion particles.
