PROBLEM TO BE SOLVED: To provide a rotary encoder capable of appropriately correcting an error even if an error of a rotation angle occurs. A rotary encoder has a rotary shaft based on an angle sensor Sp, Sq, Sr that detects an angle that fluctuates according to the rotation of the rotary shaft and the angle detected by the angle sensors Sp, Sq, Sr. Based on the rotation angle acquisition units 121p, 121q, 121r that acquire the angle sensor detection angle of the above, the reference rotation angle indicating the reference value of the rotation angle of the rotation axis calculated in a predetermined cycle, and the angle sensor detection angle. A rotation angle error calculation unit 121h for calculating rotation angle error information indicating information used for correcting an error associated with the rotation of the rotation axis is provided, and the rotation angle error calculation unit 121h stores the rotation angle in the storage unit 121b. Record the error information. [Selection diagram] FIG. 9
