A coordinate measuring instrument for measuring a shape or the like of a work to be measured by a relative displacement value between a measuring element (28) and the work (30). The measuring instrument includes displacement detectors (23, 25, 27) for detecting displacement values of the measuring element (28) relative to the work (30) in the directions of X-, Y- and Z-axes and portable detecting units (35, 38) each having a displacement detector, and these detectors are connected to an input circuit (41) of a processing unit (32) in which the data is processed to output the measured value. The detecting units (35, 38) are selectively used depending on portions to be measured of the work.
