An optical ranging device has a light emitting element, a light receiving element, a light emitting lens, and a light receiving lens. Provided between the light receiving lens and the light receiving element are a first reflection surface and a second reflection surface for changing a direction of an optical axis of a light beam condensed by the light receiving lens and guiding the light beam to the light receiving element. A single medium exists between the first reflection surface and the second reflection surface.
