Abstract
An optical ranging device includes a light emitting section provided with a semiconductor laser element having a light emitting region whose length in a first direction is more than that in a second direction intersecting the first direction. The device measures the distance to an object based on the time from light emission from the light emitting section to reception of the light by a light receiving section. A plurality of light emitting regions may be provided in the light emitting section such that they are separated in the second direction and abut or partially overlap each other in the first direction so that the light emitting regions are continuous in the first direction.
