Abstract: A method of manufacturing an electronic device includes a positioning step of positioning a first member supporting a laser diode with respect to a second member having a waveguide, a bonding step of bonding the first member and the second member together, and a checking step of checking the accuracy of positioning of the first member with respect to the second member. In the positioning step, the laser diode is energized to allow laser light to be emitted, and the laser light is allowed to be incident on the incidence end of the waveguide. In the bonding step, a bonding material is melted by irradiating the first member with heating light while the laser diode is not energized. In the checking step, the laser diode is energized again.

Abstract: A light source unit has a substrate, a light source that is mounted to the substrate. The light source includes; a first emission part that emits a forward light, the forward light being a laser light in an oscillation state; a second emission part that is located on a side opposite to the first emission part and that emits a rearward light, the rearward light being a laser light in an oscillation state; and a light leakage part located at a position different from the first emission part and the second emission part. The light source further includes a photodetector that is provided on the substrate, wherein the photodetector has a light receiving surface for detecting a leakage light that leaks from the light leakage part.
