Abstract
Disclosed is a noncontact power transmission system including a power transmission device for transmitting power to a power receiving device in a noncontact manner. The power transmission device includes a cover covering a portion of an outline of the power transmission device where the power transmission device faces the power receiving device, a base covering another portion of the outline of the power transmission device where the power transmission device does not face the power receiving device, a magnetic body arranged in a space enclosed with the cover and the base, a coil bobbin covering the magnetic body partially or entirely, and a coil wire which is wound around the coil bobbin and which generates a magnetic flux upon receiving an alternating current. The coil bobbin includes a load support.
