Abstract
A semiconductor light-emitting device having a semiconductor light-emitting chip; a high refractive index lens covering around the semiconductor light-emitting chip; and a resin having fine particles mixed therein that fills a space between the semiconductor light-emitting chip and the lens is provided. In the semiconductor light emitting device, the resin having fine particles mixed therein is composed of an optically transparent resin into which a large number of high refractive fine particles having a mean diameter of 100 nm or less and composed of a dielectric material are mixed uniformly to have a distance 200 nm or less between respective particles.
