Abstract
Provided are a semiconductor light-emitting device capable of easily adjusting the light intensity of output light and a method for producing such a semiconductor light-emitting device. The semiconductor light-emitting device includes: a substrate; a light-emitting element mounted on the substrate; and a seal layer provided on the substrate so as to cover the light-emitting element. The seal layer contains resin and inorganic pigment particles. The inorganic particles have an average particle size of 1 □m or larger and 50 □m or smaller in a volumetric basis particle size distribution by a laser diffraction scattering particle size distribution measurement method. The inorganic particles distributed at a concentration becoming thicker in a direction toward said substrate.
