Provided is an internal gear grinding method that makes it possible to grind an internal gear having arc-shaped teeth in a short amount of time. To this end, an internal gear having arc-shaped teeth and a threaded grindstone with a barrel shape having blades with a shape corresponding to the arc shape of the teeth are engaged at a predetermined axis intersection angle, and the internal gear and the threaded grindstone are made to rotate in synchronization with each other so that the tooth surface of the internal gear is ground by the blade surface of the threaded grindstone.
