Abstract
A contact probe includes a stylus, a spring, a magnetic body, and a permanent magnet. The stylus is displaceable in an X direction and a tip of the stylus makes contact with a measured object. A first end of the spring is fixated and a second end provides spring force along the X direction. A position of the magnetic body is fixated with respect to the stylus. The permanent magnet is arranged separated from the magnetic body so as to generate a magnetic force along the X direction between the magnetic body and the permanent magnet.
