PROBLEM TO BE SOLVED: To further improve balance between profile accuracy and surface roughness than before by automating and controlling work, improve the profile accuracy and surface roughness and reproducibilities thereof, in a polishing method and a polishing device of a gear. SOLUTION: This polishing device of the gear is so constructed that a gear G is held to freely rotate around an axis, and a working rotor 111 with a tooth space is rotated and abutted on the outer peripheral part of the gear through abrasive grains, thereby polishing the gear while the gear is rotated. The polishing device has a calibration process of relatively approaching the gear and the working rotor by a moving mechanism 113 to detect stress between the gear and the working rotor by a stress sensor 122, and obtaining the relative position relationship between the gear and the working when the stress reaches a predetermined threshold, and a process of performing polishing work under a polishing condition on the basis of the relative position relationship.
