Light-emitting device
The light-emitting device includes: a substrate which has a single layer structure in which a conductive member is partially provided on a surface of the substrate; a plurality of light-emitting elements which are directly provided on the surface of the substrate so as to be electrically connected with the conductive member; a first light reflection resin layer; a second light reflection resin layer which is provided in a looped shape on the surface of the substrate so as to surround an area in which the plurality of light-emitting elements are provided; and a sealing resin which covers the plurality of light-emitting elements. In the area in which the plurality of light-emitting elements are provided, the conductive member is covered with the first light reflection resin layer, the conductive member, which is provided under the second light reflection resin layer, is covered with the second light reflection resin layer directly, and a printed resistor, which is provided under the second light reflection resin layer, is covered with the second light reflection resin layer via the first light reflection resin layer. This makes it possible to provide the light-emitting device which (i) reduces absorption of light so as to achieve excellent light extraction efficiency, and (ii) is highly reliable.
