Abstract
To reduce wiring inductance between a semiconductor laser and a laser driver on a ranging device.SOLUTION: The ranging device includes a substrate, a laser driver, a semiconductor laser, and a light-receiving unit. The substrate incorporates a laser driver. The semiconductor laser is mounted on one surface of the substrate, occupying a predetermined area, and less than or equal to 50% of its area is arranged to be superimposed on the laser driver to emit irradiating light. A connecting wiring electrically connects the laser driver and the semiconductor laser via connection vias provided on the substrate. The light-receiving unit receives reflected light from an object with respect to irradiated light from the semiconductor laser.SELECTED DRAWING: Figure 14
