A power transmission circuit is connected to a power transmission coil having a coil aperture. The power transmission circuit includes a conductive or magnetic power-transmission-coil near member opposed to the coil aperture of the power transmission coil, and a repeating coil arranged on a side opposite to a side on which the power-transmission-coil near member is arranged with respect to the power transmission coil and coupled to the power transmission coil at least via a magnetic field. When a shortest distance between the power transmission coil and the power-transmission-coil near member is expressed as (dt1) and a shortest distance between the power transmission coil and the repeating coil is expressed as (dt2), dt2≤dt1.
