Zusammenfassung:A light-emitting device includes: a light-emitting element; a first light-transmissive member located on an upper surface of the light-emitting element and containing substantially no phosphor; a second light-transmissive member located on an upper surface of the first light-transmissive member and containing a first phosphor; and a third light-transmissive member covering an upper surface of the second light-transmissive member and a lateral surface of the tight-emitting element and containing a second phosphor; wherein a refractive index of a resin material serving as a base material of the second light-transmissive member is higher than a refractive index of a resin material serving as a base material of the first light-transmissive member; and wherein a refractive index of a resin material serving as a base material of the third light-transmissive member is equal to or higher than the refractive index of the resin material serving as the base material of the second light-transmissive member.
