A mounting substrate includes: a wiring substrate; and a plurality of optical elements mounted on a mounting surface of the wiring substrate, and each having a first electrode and a second electrode. The wiring substrate includes a support substrate, a plurality of first wires, and a plurality of second wires. The first wires and the second wires are provided within a layer between the support substrate and the mounting surface. The first wires are electrically connected with the first electrodes. The second wires are electrically connected with the second electrodes, and each have cross-sectional area larger than cross-sectional area of each of the first wires. |
