A form measuring sensor (33) includes a stylus (40), a body (60) for holding the stylus (40) through an adaptor (50), the adaptor (50) including a stylus attachment (51) for the stylus (40) to be attached, a body attachment (52) to be attached to the body (60), and an elastically deformable connector (53) for connecting the stylus attachment (51) and the body attachment (52), where the sensor (33) and a threaded hole (100) are relatively moved to cause an elastic deformation of the connector (53) allowing a displacement of the stylus (40) in accordance with surface configuration of the threaded hole (100), so that the elastic deformation of the connector (53) is detected by a strain gauge (71) to detect the displacement of a contact portion (42A) to collect continuous configuration data of the threaded hole (100) within a short period of time.
