<P>PROBLEM TO BE SOLVED: To provide a calibration target which enables camera calibration with stable accuracy. Ž<P>SOLUTION: The calibration target 101 for camera calibration which is used when cameras mounted on vehicles in different states are calibrated in the same facility, is constituted of a plurality of similar figures different in size. These similar figures are arranged so that figures smaller in size are in figures larger in size while preventing their sides from touching each other. A continuously-linking figure having, as a guard area 104, an area predetermined in breadth from the sides constituting a small figure between the sides constituting the small figure and the sides constituting a larger figure, is used as a marker 105, and a plurality of such markers are arranged.
