Abstract
A feeding structure of a housing with an antenna, in which a flat antenna can be attached inconspicuously to the outer surface of the housing which is hard to be affected by a metal component and power can be supplied to the flat antenna without providing a through hole causing inferior appearance. The feeding structure of the housing with an antenna comprises a housing 2, a decorative film 3 covering at least a part of the outer wall face of the housing 2, a flat antenna 6 held between the outer wall face of the housing 2 and the decorative film 3, and an electrode 7 provided on the inner wall face of the housing 2. In the feeding structure, a capacitor is formed by arranging a feeding part 6a of the flat antenna 6 and the electrode 7 opposite to each other in both faces of the housing 2 and power transmission and communication are performed in a noncontact manner for the flat antenna 6 on the outside of the housing 2 from the inside of the housing 2 by connecting an inductor 8 with the electrode 7.
