Abstract
A detection device, including: one or a plurality of magnetic coupling elements configured to have one or a plurality of coils; and a detection unit that measures or calculates an effective resistance values of the magnetic coupling elements or an effective resistance value of a circuit including at least the magnetic coupling elements and determines a presence or absence of a foreign substance based on a change in the effective resistance value.
