Claim:
1. A light emitting device, comprising: a substrate having a main surface; an inner portion provided on said main surface and containing a semiconductor light emitting element that emits primary light and a fluorescent particle that absorbs a part of the primary light and emits secondary light; an outer portion having a refractive index n and covering said inner portion, wherein said outer portion has an outer circumferential surface exposed to the atmosphere, when a minimum spherical circumference that includes overall said inner portion and is concentric with said outer circumferential spherical surface has a radius r in a cut surface where at least a part of said outer circumferential spherical surface takes a shape of an arc having a radius R, a relationship of R>r·n is satisfied; wherein said outer portion is formed of a single transparent layer; said inner portion is a phosphor layer containing said fluorescent particle, and said phosphor layer is provided to be in direct contact with said semiconductor light emitting element and directly cover said semiconductor light emitting element; and wherein said fluorescent particle is provided only in said inner portion, of said inner portion and said outer portion.
