Abstract
A light-emitting device in which the emission intensity of light-emitting elements is improved by making heat generated by light emission of the light-emitting elements be effectively released is provided. The light-emitting device includes a mounting substrate including a mounting region, light-emitting elements mounted on the mounting region, a sealing resin which contains a phosphor and integrally seals the light-emitting elements, and at least one heat transfer member which is arranged among the light-emitting elements on the mounting region, is embedded in the sealing resin, and has a higher thermal conductivity than the sealing resin.
