PROBLEM TO BE SOLVED: To reduce misdetection while maintaining a wide detecting range in a target detecting technique using a laser sensor. SOLUTION: A target detecting method detects a target by emitting a laser beam diagonally downward from an installing position of a laser emitting and receiving portion. The method includes the steps of: obtaining information on the distance between the laser emitting and receiving portion and an object to be detected; determining, when the object to be detected approaches the laser emitting and receiving portion, whether the tracking of the object to be detected is suspended or not; and determining, when the tracking of the object to be detected is suspended, whether the object to be detected is the target or a non-target based on the information on the distance immediately before the tracking of the object to be detected is suspended.
