Claim:
1. A light emitting device comprising: a base that has a recessed portion and an element mounting surface located at a bottom of the recessed portion; a light emitting element that is mounted on the element mounting surface; and a coating member that is constituted by a single layer that fills the recessed portion and coats an upper part of the light emitting element, the coating member containing a fluorescent material that is excited by light from the light emitting element, wherein an uppermost surface of the coating member is exposed to an ambient environment, wherein the light emitting element is configured such that a maximum light intensity of light emitted into the coating member from the light emitting element is in a directly upward direction, wherein the light emitting device is configured such that a light emission chromaticity of the light emitting device exhibits a substantially rectangular wave profile when measured at an uppermost surface of the coating member, in a lateral direction, in a portion that, when viewed from a location above the light emitting device, corresponds to a projected area of the light emitting element in the lateral direction, wherein said substantially rectangular wave profile includes a central region having a light emission chromaticity indicative primarily of blue light, and lateral regions having a light emission chromaticity indicative primarily of yellow light, and wherein an entirety of the fluorescent material is located at a position other than directly above the light emitting element.
