Abstract
An electronic unit includes an electricity reception section that receives power transmitted using one of a magnetic field and an electric field, a secondary battery that is charged based on a received power received by the electricity reception section, and a state notification section that provides notification to outside as to a state of its own unit. A charging period during which the secondary battery is charged based on the received power and a non-charging period are set in a time-divisional manner. The state notification section notifies of the unit state based on the received power in both of the charging period and the non-charging period.
