Abstract

Provided is a magnetic detection device () having a simple configuration and being capable of stably detecting fine portions of a coin. The magnetic detection device () comprises an excitation coil (LX) that generates an alternating magnetic field in a transport path for transporting a coin in a first direction, and a plurality of detection coils (L, L) that are arranged at a predetermined pitch in a second direction and that output a detection signal based on an induction voltage caused by the alternating magnetic field. Each of the plurality of detection coils (L, L) outputs a detection signal on the basis of the induction voltage induced by the alternating magnetic field, which changes due to the coin being transported along the transportation path.
