To provide a light emitting device that makes it possible to form a surface light emitting apparatus of less unevenness in luminance. The light emitting deviceof the present invention comprises a light emitting element, connecting terminalsconnected with the light emitting element, a packagewhich has a recesswherein the light emitting elementis mounted and from which a part of each connecting terminalis projected outward, an openingof the recessbeing elongated in one direction, wherein both side walls of the recesspositioned in the longitudinal direction of the recessare inclined surface, an angle &#x3b8; between both the inclined surfacesbeing 90 degrees or more. In the light emitting deviceof the present invention, light emitted by the light emitting elementis spread sufficiently in the longitudinal direction of the openingso as to produce a band-shaped beam. As a result, when a plurality of light emitting devicesare disposed along the longitudinal direction of the light receiving surfaceof the light guide platefor constituting the surface light emitting apparatus, unevenness in luminance can be suppressed from occurring as dark portions are less likely to be generated between adjacent light emitting devices
