Abstract: A light emitting device comprises a package having a recess; a light emitting element mounted in the recess of the package; a light transmissive member provided above the light emitting element; a sealing resin that seals the recess of the package; and a fluorescent material contained in the sealing resin. The fluorescent material is distributed to a side of the light emitting element in a greater amount than to above the light emitting element, a side surface of the light emitting element is exposed to the sealing resin, and a portion of the light transmissive member protrudes from the sealing resin.

Abstract: A light emitting device includes a base that has an element mounting surface, a light emitting element that is mounted on the element mounting surface and that has maximum light intensity in a directly upward direction, and a coating member that contains a fluorescent body that is excited by light from the light emitting element, and that is constituted by a single layer that coats an upper part of the light emitting element. The fluorescent body exists at a position other than directly above the light emitting element.
