Abstract: An optical measurement apparatus performs an optical axis adjustment with respect to a reference surface and obtains high measurement accuracy. In an outer surface of a box-shaped light receiving housing, reference surfaces which become a reference at the time of placing the light receiving housing. In the light receiving housing, the light receiving side telecentric lens is mounted. An imaging element holder holding a two-dimensional imaging element is provided on an inner surface opposite to an introducing opening of the light receiving housing, and the two-dimensional imaging element is mounted in a manner of being capable of adjusting its position and posture.
