A method of correcting a position of a robot includes: a correction step of rotating an arm around a first axis to detect a rotation angle around the first axis when a target blocks detection light, and locating the first axis, a third axis, and the target on an identical straight line by rotating the arm and/or a hand around the first axis, a second axis, and/or the third axis based on a detection result; and a correction amount arithmetic step of obtaining rotation angle correction amounts of the second axis and the third axis based on the rotation angle of each rotation axis acquired after the correction step in a first posture.
