Abstract: An intruder detection system includes a leaky transmission path of a transmission side and a leaky transmission path of a receiving side, both of which has a plurality of leaky points existing in a direction to which the respective leaky transmission path extends, and the intruder detection system further includes an intrusion location detection unit which detects an intrusion location of an intruder on the basis of each signal, which is received in a receiving circuit of the receiving side, affected by the leaky electric wave at each of the leaky points. The intruder detection system further includes a detection table which associates a detectable intrusion location with a detection area, and if intrusion location detection information of the intrusion location detection unit corresponds to a detection area of the detection table, a detection result is output.
