Mounting substrate and optical unit

摘要

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.

1. 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, 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 without avoiding the locations beneath the respective optical elements.
