Abstract: A light emitting device includes a resin molding, first and second leads, and a light emitting element. The resin molding includes a front surface defining an opening, and a lower surface adjacent to the front surface. The first and second leads each includes an outer lead portion and an inner lead portion. The outer lead portion protrudes from the lower surface of the resin molding, and includes a bent portion bent along the lower surface. A surface on an inner side of the bent portion including a first recessed section. The inner lead portion includes an embedded portion embedded in the resin molding, and an exposed portion exposed in the opening. A surface of the embedded portion opposite from the surface where the first recessed section is provided includes a second recessed with a part of the resin molding being positioned in the second recessed section.

Abstract: A planar light source includes a light source, a light guide member, a wiring substrate, a light reflecting sheet and a pair of conducting members. The light source has a pair of electrodes on one face. The light guide member covers the light source while the electrodes are exposed from the light guide member. The wiring substrate has a wiring layer. The light reflecting sheet is interposed between the light guide member and the wiring substrate and defining a pair of first through holes at positions aligned with the electrodes on a one-to-one basis. The conducting members are respectively disposed in the first through holes and electrically connecting the electrodes to the wiring layer.
