A wireless power feeding method includes causing each of a plurality of power transmitters to acquire power amounts for power received by one or more of a power receptors which are targets for power transmission, determining a first power amount which is the smallest out of acquired power amounts, and adjusting a power transmission direction to be a direction in which the power received by the power receptor which has received the first power amount is maximum. Each of the plurality of power transmitters are caused to transmit power in the adjusted power transmission direction and leaked power amounts for leaked power, which is received by the power receptors that are the targets for power transmission of other power transmitters, are acquired as leaked power amounts to the power transmitters for which the targets for power transmission are the power receptors which receive the leaked power.
