Abstract: A light emitting device includes one or more light emitting elements, a light transmissive member, a first light reflective member and a second light reflective member. The light transmissive member is disposed on the one or more light emitting elements and having a first upper surface, a lower surface, first lateral surfaces, and second lateral surfaces each positioned on an outer side of a corresponding one of the first lateral surfaces. The first light reflective member covers the first lateral surfaces. The second light reflective member is disposed on lateral surfaces of the first light reflective member, the second lateral surfaces of the light transmissive member, and lateral surfaces of the one or more light emitting elements.

Abstract: A light emitting apparatus comprises an electrically insulating base member; a pair of electrically conductive pattern portions formed on an upper surface of the base member; at least one light emitting device that is electrically connected to the pair of electrically conductive pattern portions; and a resin portion that surrounds at least a side surface of the at least one light emitting device and partially covers the pair of electrically conductive pattern portions. Each of the pair of electrically conductive pattern portions extends toward a periphery of the base member from resin-covered parts of the electrically conductive pattern portions. At least the resin-covered parts of each of the electrically conductive pattern portions has at least one elongated through hole extending in a direction in which the electrically conductive pattern portions extend from the resin-covered parts, wherein the resin portion contacts the base member via the through holes.
