Abstract
To provide an electronic device having an antenna function without having to enlarge the size of the device. The electronic device includes a shielding case, a feeding loop, an operation knob, and an antenna element. The shielding case blocks passage of electromagnetic waves. The feeding loop is a conductor that is disposed annularly along a prescribed plane outside the shielding case and is connected to a radio communication circuit encompassed within the shielding case. The operation knob is configured to be rotatable around a specific axis that passes through an annular ring formed by the feeding loop. The antenna element is an open-loop conductor fixed to the operation knob.
