摘要

There are provided a detector and the like that are capable of conveniently detecting conductor or a circuit including a coil. The detector includes a detecting section that determines a Q value or a degree of variation thereof in a circuit including a coil capable of electromagnetic coupling with an external object and that performs detection concerning a state of the electromagnetic coupling with the external object based on a determined result.
