Provided is a coordinate measuring device which can easily perform accurate measurement. A coordinate measuring device is provided with a sub-imaging unit, a display unit, and a probe. The probe includes a stylus. The stylus has a contact part that is brought into contact with a measurement target in order to measure the measurement target. The sub-imaging unit is provided in the probe so as to have constant positional relationships, and captures an image of at least part of the measurement target. The image of the measurement target obtained by the sub-imaging unit is displayed as a captured image on the display unit. Based on calculated positions of the probe and the positional relationships of the sub-imaging unit, an image showing a measurement position on the measurement target, with which the contact part is to be brought into contact, is displayed on the captured image.
