摘要： 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.

摘要： An antenna device includes a feed coil and a sheet conductor. The feed coil includes a magnetic core and a coil-shaped conductor, which is formed around the magnetic core. An RFIC is connected to the feed coil. The sheet conductor has a larger area than the feed coil. A slit that extends from a part of the edge of the sheet conductor toward the inner side of the sheet conductor is formed in the sheet conductor. The feed coil is arranged such that the direction of the axis around which the feed coil is formed is parallel to the directions in which the sheet conductor extends. The feed coil is arranged in such a manner that the feed coil is close to the slit and one of coil openings at the ends of the feed coil faces the slit.
