Provided is a calibration apparatus including: an acquisition unit for acquiring a detection position of a mobile body for each actual position of the mobile body; a calculation unit for calculating, for a detection position of each actual position of the mobile body, an error between a slit position signal for detecting a slit position and an ideal slit number corresponding to the actual position; a determination unit for determining whether two or more actual positions having at least partially different slit numbers in units of first slits of a predefined number correspond to a same detection position; and a generation unit for generating, in response to the two or more actual positions corresponding to a same detection position, a correction value for correcting an error by a magnitude between errors at the two or more actual positions with respect to the slit position signal at the detection position.
