An electronic device is to be worn by a user and includes an antenna and a storage compartment that stores the antenna. In a state of the electronic device being worn by the user, the storage compartment is positioned at a side of the user's head. The antenna is capable of selectively adopting a stored state and a deployed state, the antenna being stored in the storage compartment in the stored state, and a greater portion of the antenna being separated from the storage compartment in the deployed state than in the stored state.

Electronic device

Provided is an electronic device in which, if an antenna element is formed on the surface of a housing, restrictions on the formation of the antenna element are less likely to arise. The following are provided: a rear case, an antenna element, and a power supply unit that supplies power to the antenna element. The antenna unit comprises a first section that is formed by applying a conductive material onto a first main surface of the rear case, and a second section. A dielectric or an insulator is interposed between the first section and the second section.

A communication repeater comprises a transmitting and receiving that performs wireless communication with a communication device, a power-line carrier communication unit that performs power-line carrier communication with the communication device, and a control unit. The control unit selects either one of the wireless communication and the power-line carrier communication according to conditions.
