Abstract
There is provided an electronic device for enabling the user to recognize the relative position of the electronic device to a power supply device such as a charger. An electronic device 11B includes a main coil 18 having a conductor wire wound around a main point 33 for receiving power for charging a secondary battery from a charger 12, a position detection coil 31 placed at a first point in the electronic device 11B, a position detection coil 32 placed at a second point in the electronic device 11B, and a position shift display section 39. If magnetic flux density detected by the position detection coil 31 is higher than magnetic flux density detected by the position detection coil 32, the position shift display section 39 provides notification of prompting the user to move the electronic device 11B from the second point to the first point, and if the magnetic flux density detected by the position detection coil 32 is higher than the magnetic flux density detected by the position detection coil 31, the position shift display section 39 provides notification of prompting the user to move the electronic device 11B from the first point to the second point.
