Mounting substrate and optical unit

A mounting substrate, comprising:

• 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,
• wherein:
• 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 being provided within a layer between the support substrate and the mounting surface,
• the first wires are electrically connected with the first electrodes, and
• the second wires are electrically connected with the second electrodes and are disposed within a layer between the support substrate and a layer that includes the first wires, and each have cross-sectional area larger than cross-sectional area of each of the first wires, wherein
• the plurality of first wires extend in a first direction and are disposed side-by-side in a direction intersecting with the first direction, the first wires being disposed to avoid locations beneath the respective optical elements, and
• the plurality of second wires extend in a second direction intersecting with the first direction and are disposed side-by-side in a direction intersecting with the second direction, the second wires being disposed to avoid the locations beneath the respective optical elements.

An optical unit, comprising:
