Abstract
A contactless charging device includes a placement plate on which a portable apparatus is placed, a charging coil, a position detector having a position detection coil, a foreign object detector having a foreign object detection coil, an alarm, and a controller. The position detection coil and the foreign object detection coil are disposed on or under the placement plate. The controller drives the alarm if the foreign object detector detects the presence of a conductive foreign object on the placement plate, and then the position detector detects the portable apparatus on the placement plate.
