A measuring probe includes a stylus having a contact part to be in contact with an object to be measured, an axial motion mechanism having a moving member that allows the contact part to move in an axial direction, and a rotary motion mechanism having a rotating member that allows the contact part to move along a plane perpendicular to the axial direction by means of rotary motion. The measuring probe includes a main body housing that supports the axial motion mechanism, a module housing that supports the rotary motion mechanism, and a displacement detector supported by the main body housing for detecting displacement of the moving member. The measuring probe with this configuration ensures high measurement accuracy while keeping a low cost.
