A wireless power transmission system includes a power transmitting device and a power receiving device. The power transmitting device includes: a first inverter circuit to output charging power to be directed to power transmission; a power transmitting antenna; and a first control circuit to control the first inverter circuit. The power receiving device includes: a power receiving antenna; and a trigger application circuit to apply, to detecting power to be supplied to the power receiving antenna, a trigger signal for informing of the power transmitting device of the presence of the power receiving device. Upon detecting the trigger signal, the first control circuit causes the first inverter circuit to begin outputting the charging power.
