PROBLEM TO BE SOLVED: To provide a gear processing method and a tool shaping method capable of eliminating waving in tooth form, and reducing gear noise. SOLUTION: In this processing method, a gear is manufactured in a gear generating method using a worm tool 21, with the phases of the worm tool 21 and a workpiece 22 shifted during processing, while simultaneously the worm tool 21 is moved in the workpiece axis direction. By moving the worm tool 21 in the tool axis direction, its phase to the workpiece can be shifted. For the worm tool 21, a tool trued in a processing machine, a tool trued outside the processing machine, an electrodeposition worm tool, or a cemented carbide hob or other hob can be used. For phase deflection quantity between the worm tool 21 and the workpiece 22, a 5-90 deg. range is preferable as rotation angle shift quantity of the worm tool 21 per rotation of the workpiece 22.
