Abstract
In a mobile-terminal charging device, a controller performs a safety operation in a case where a resonance frequency detected by a foreign object detection coil corresponding to a location where a charging coil is present is higher than a reference resonance frequency stored in a memory, or a resonance voltage detected by a foreign object detection coil corresponding to a location where the charging coil is present is lower than a reference resonance voltage stored in the memory.
