See full text

An electronic unit includes: an electricity reception section configured to receive power fed from a power feeding unit using a magnetic field; a voltage detection section configured to detect a received voltage supplied from the electricity reception section; and a control section, wherein while preliminary power feeding at a lower power than main power feeding is performed from the power feeding unit, and when a received voltage detected by the voltage detection section is equal to or higher than a predetermined threshold voltage, the control section performs voltage reduction control so as to decrease the received voltage to lower than the threshold voltage.
