A measuring instrument comprising a stylus displaced following a work, the instrument further comprises a corrector for correcting a displacement in the translation axis direction value according to a height detection axis direction value of the stylus position in a plane specified by the height detection axis and the translation axis, the corrector comprising a calibration measuring device that obtains the calibration measurement data including the displacement information of the translation axis direction value corresponding to the height detection axis direction value of the stylus by moving the stylus; a correction parameter setting device that determines a correction parameter best suited for correcting the measurement error due to the vertical movement error of the stylus based on the displacement information of the stylus; and a measurement data correcting device that corrects a measurement data by using the correction parameter.
