A mobile body is driven by power that is wirelessly transferred from a non-contact power supply device including a power transmission resonator that transmits power in accordance with a non-contact power supply method. The mobile body includes a power reception resonator, a power storage, a motor, a controller, and at least two wheels driven independently of each other by the motor, the at least two wheels including a first movement axis and a second movement axis with an axial orientation different from that of the first movement axis, and moving the mobile body along the first movement axis and the second movement axis. When the mobile body moves to a power supply target range, the controller controls the motor based on power reception status information indicating a status of power reception by the power reception resonator, and moves in a flat plane direction.
