Abstract:
A detection device includes a coil configured to be electromagnetically coupled with an outside, and a detection section connected to a circuit including the coil. The detection section is configured to measure a Q value of the circuit using an alternating-current signal at a frequency different from a frequency of an alternating-current signal of contactless power feed.
