PROBLEM TO BE SOLVED: To easily and accurately measure the size of an object to be measured such as a retainer used for a ball bearing that abuts on a spherical body and is positioned. SOLUTION: This measuring device 100 measures a distance between faced measured surfaces 32a and 33a. At least one of the measured surfaces 32a and 33a has the spherical body 20, the distance between the measured surfaces 32a and 33a nipping the object to be measured 10 via the spherical body 20 is measured.
