Abstract

A three-dimensional measurement probe that is less likely to break, that is of long lifespan, and that is of low cost, capable of measuring the shape and the like of a measuring object such as an aspheric lens with higher precision is realized. A magnetic force for preventing rotation and axial displacement of a small slidably moving shaft part is generated by constructing a magnetic circuit by a magnet attached to a small air bearing part, a yoke, and a magnetic pin attached to the small slidably moving shaft part. The three-dimensional measurement probe is able to perform measurement from below and from the side since the magnetic force is non-contacting.
