PROBLEM TO BE SOLVED: To provide a calibration method for a distance detection means in a mobile element such as an autonomous mobile robot, in which calibration work to a distance detection means (distance sensor) installed on the mobile element can be easily performed to achieve correct results of calibration. SOLUTION: This calibration method is for a distance detection means in a mobile element provided with a plurality of drive wheels to travel, a light receiving part to receive reflection light of radiation light projected from a light emitting part to a travel surface in a travel zone, and the distance detection means for detecting distance to the travel surface in the travel zone. The distance detection means is calibrated using a target surface vertically provided on the travel surface at the farthest part in a possible detection range of the distance detection means in the travel zone of the mobile element.
