Abstract
The present technique reduces the wiring inductance between a semiconductor laser and a laser driver in a semiconductor laser driving apparatus. A semiconductor laser driving apparatus includes a substrate, a laser driver, and a semiconductor laser. The substrate incorporates the laser driver. The semiconductor laser has at least one light emitting point. The semiconductor laser is mounted on one surface of the substrate in such a manner that an electrode of the light emitting point and a pattern of the substrate are connected to each other via a bump. Connection wiring electrically connects the laser driver and the semiconductor laser to each other with a wiring inductance of 0.5 nanohenries or less. A sealing portion seals a connection terminal portion of the semiconductor laser for the substrate.
