A connection jack of an external antenna is provided to be attachable to and detachable from a terminal easily, and to increase a receiving rate and a frequency bandwidth by connecting an external antenna to an end portion of a terminal antenna. A head unit(21) of a terminal antenna(2) is coupled to a groove(53), and a conducting unit(51) is mounted inside the groove and electrically connected to an external antenna unit. A connection jack(5) is connected to the external antenna unit through a cable at which a signal line and a shield line are prepared. The conducting unit is connected to the signal line. The groove includes an opening unit(531) to which the head unit is inserted, and also contains a suspending end(532) which supports a body unit(22) of the terminal antenna. |
