A power transmitter includes: a first coil that wirelessly transmits the electric power to a second coil of a power receiver; a converter including a DC/AC converter that converts DC electric power into AC electric power and supplies the AC electric power to the first coil; and a controller that brings a power value of the DC electric power or the AC electric power close to a power command value by frequency control of changing a frequency of the AC electric power. The controller performs, when the frequency at which the power value reaches the power command value is included in a used frequency band used by another device, frequency change process of changing the frequency so that the frequency becomes a frequency different from the used frequency band while performing constant power control of maintaining a state in which the power value matches the power command value.
