The present invention addresses the problem of checkting defects of a rail for a vehicle with a high SN ratio. A detction device (2) for generating check data related to the defects of a railway rail RR (rail for a vehicle) is provided with an oscillating coil 1 (211) and an oscillating coil 2 (211) that are disposed on the surface opposite the railway rail RR and generate AC magnetic fields whose directions are opposite to each other, and a receiving coil (212) that is positioned between or in the vicinity the oscillation coils and that outputs a magnetic field waveform based on the magnetic fields received from the oscillating coils as the check data.
