Abstract
A distance measuring device measures a distance to a target object with high accuracy by reducing stray light in a probe tip end section. In the distance measuring device, the probe tip end section has an optical path switching element that switches an optical path of measurement light incident from the optical element, at a tip end of the probe tip end section. A material of at least a part of the probe tip end section provided at a position opposite to a fifth surface absorbs the measurement light.
