A compact magnetic object detection device with high degree of freedom for installation can be provided. The magnetic object detection device includes magnetic field generating mechanism for radiating an alternating magnetic field in a vicinity space; one or a plurality of loop antennas which convert the magnetic field in the vicinity space into an electric signal; determining mechanism for analyzing an existence of magnetostriction and determining an existence of a magnetic object, the magnetostriction generated by the magnetic object existing in the vicinity space based on the electric signal of each of the loop antennas. An installation member, attached with at least the magnetic field generating mechanism and each of the loop antennas, has a pole shape.
