Abstract
A winding of a transmission coil included in a power transmission device of a contactless power feed apparatus and serving to transmit AC power to a power reception device contactlessly is formed of a wiring pattern provided on a substrate. The transmission coil is divided into partial coils arranged coaxially. Each of the partial coils is formed such that, among the partial coils, a number of turns of a winding included in a partial coil is larger as the partial coil is located more outwardly.
