Measuring probe

A measuring probe comprising:

• a stylus having a contact part to be brought into contact with an object to be measured;
• a probe housing capable of supporting the stylus on an axial center;
• detection elements capable of detecting a movement of the contact part;
• a signal processing circuit that processes outputs of the detection elements;
• and
• a plurality of supporting members in an axial direction of the probe housing, the supporting member having a rotationally symmetric shape and allowing for an attitude change of the stylus, wherein
• four said detection elements are disposed at fourfold symmetric positions in at least one of the plurality of supporting members that includes a deformable arm part, and
• the signal processing circuit includes a first processing part that processes the outputs of the detection elements to output three displacement signals representing displacement components of the contact part in mutually perpendicular three directions, respectively.
