<p>On the undersurface of a metal cover, a feeding coil module is disposed. In a casing, a printed circuit board is included. At the printed circuit board, a ground conductor, a feeding pin, and a ground connection conductor are disposed. When the metal cover on which the feeding coil module is disposed is mounted on the casing, the feeding pin is in contact with a connection portion of the feeding coil module and is electrically connected thereto. The ground connection conductor is in contact with the metal cover and connects the metal cover to the ground conductor. The ground connection conductor is disposed either side of a slit outside an area in which the current density of an induced current flowing through the metal cover is in the range from its maximum value to approximately 80% of the maximum value or one side of the slit in the area.</p> |
