A contactless power transmitting device that contactlessly transmits electric power to a power receiving device includes a transmitting unit and a power transmission controller. The transmitting unit transmits electric power at a variable transmission frequency. The power transmission controller sets the transmission frequency, based on frequency information concerning a frequency of a broadcast wave that can be received at a position of the contactless power transmitting device. The power transmission controller sets the transmission frequency so that one of the transmission frequency and the frequency of the broadcast wave differs from an integer multiple of the other thereof.
