A power transmitting device includes a power transmitting unit, a first tuner, and a second tuner, and a controller. The power transmitting unit is configured to transmit AC transmission power to a power receiving device in a non-contact manner. The first tuner is configured to discretely tune a frequency of the transmission power. The second tuner is configured to discretely tune a resonance frequency of the power transmitting unit. The controller is configured to control the first and second tuners such that the number of tunings using one tuner having the smaller frequency tuning interval of the first and second tuners is larger than the number of tunings using the other tuner.
