    • PROBLEM TO BE SOLVED: To provide an intruder detector economically easy to manufacture with extension of detecting distance and improvement in detecting accuracy.
      SOLUTION: The intruder detector 16 which is adapted to determine existence of an intruder based on change of radio waves received by a receiving-side leak transmission path 6 juxtaposed with a transmitting-side leak transmission path 5 and receiving leak current from the transmission path 5 comprises a plurality of reference spectrum diffusion signal generation means 9-1 to 9-150 and a plurality of correlation means 10-1 to 10-150 for collating an output reference spectrum diffusion signal from the reference spectrum diffusion signal generation means with a received signal from the receiving side leak transmission path, both the means being constituted on a common sensor card 13; and a setting means 17 for adjusting detection accuracy determined by the reference spectrum diffusion signal generation means and the correlation means. An intrusion position of intruder is detected from the respective outputs of the plurality of correlation means.
