| 主权项 | 1. A detecting apparatus comprising: one or a plurality of magnetic coupling elements that include a plurality of coils; a positioning unit disposed near at least one coil from among the plurality of coils included in the one or plurality of magnetic coupling elements; a magnetic shielding material that reduces outward magnetic flux leakage, and is able to maintain a position relationship between the one or plurality of magnetic coupling elements and the positioning unit; and a detector that measures an electrical parameter related to the one or plurality of magnetic coupling elements or to a circuit that at least includes the one or plurality of magnetic coupling elements, and determines from a change in the electrical parameter whether a foreign matter that generates heat due to magnetic flux is present. | ||
