摘要:An antenna has an electromagnetic interference suppressor (3) which comprisesa composite magnetic member containing soft magnetic powder having an oxide film
layer and which covers a part of the periphery of the antenna. It is preferable that theelectromagnetic interference suppressor covers one side or a half of the periphery of theantenna. The antenna may comprise a first antenna portion (10) slidably held by ahousing of a radio apparatus, and a second antenna portion (20) connected to one end ofthe first antenna portion. In this case, the electromagnetic interference suppressor isarranged in at least one of the first and the second antenna portions. The first antennaportion is slidably held by a holder portion (4) fixedly attached to the housing of theradio apparatus. A stopper portion (5) is fixedly attached to one end of the first antennaportion to serve as a feeding portion for the first antenna portion when the antenna ispulled out. The second antenna portion is connected to the other end of the firstantenna portion through a sleeve portion (6).
