Abstract:
1. A light-emitting device comprising: a substrate; a plurality of pads arranged on the substrate, each of the pads having electric conductance and a surface on which a reflecting layer formed by electroplating is provided; a plurality of light-emitting elements which are mounted on the pads; and a depressed part which is left on the substrate, the depressed part being formed on the substrate by removing a pattern on the substrate, by which the pads are electrically connected, wherein, the pattern includes a plurality of connection lines which are guided from the pads to a plurality of positions on the substrate; the depressed part includes a plurality of cutoff parts formed in the positions to which the connection lines are guided; the cutoff parts are opened to an edge of the substrate and distant from one another; the substrate includes a first surface on which the pads and the connection lines are arranged, a second surface which is positioned on a side opposite to the first surface, and an outer peripheral surface which connects the first surface with the second surface; and each of the cutoff parts is opened to a corner part of the substrate which is defined by the first surface and the outer peripheral surface, and has a bottom which connects to the outer peripheral surface.
