Abstract

In a power and data transmission method which can transmit power and information (data) simultaneously and contactlessly, and an apparatus therefor, a pair of coil units are magnetically coupled to each other. Each of the coil units has: a power transmission coil configured by a coil which is wound in a plane, and a magnetic shield member which is placed on a rear surface of the coil; and an information transmission coil configured by a coil which is wound in a plane, and a magnetic shield member which is placed on a rear surface of the coil, the coil diameter of the information transmission coil is made different from that of the power transmission coil, and the information transmission coil and the power transmission coil are stacked. Data are transmitted while power is transmitted.
