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.
