Is fixed on the shield case. With this configuration, it is possible to keep the chip antenna 5 away from the front case 3 and to suppress deterioration of the antenna radiation characteristics when the chip antenna 5 is brought into contact with the ear during a portable wireless communication. Further, the space for mounting the chip antenna 5 is limited to the resin circuit board 1.
Since there is no need to mount the circuit board on the upper side, the layout of the circuit board becomes easy and the size of the board can be reduced. Further, unlike the case where the circuit board is mounted on a resin circuit board, the characteristics are not deteriorated due to the influence of components arranged around the circuit board.

With this configuration, it is possible to keep the chip antenna 5 away from the front case 3 and to suppress deterioration of the antenna radiation characteristics when the chip antenna 5 is brought into contact with the ear during a portable wireless communication. Also,
Since the space for mounting the chip antenna 5 does not have to be provided on the circuit board 1 made of resin, the layout of the circuit board becomes easy and the size of the board can be reduced. Further, unlike the case where the circuit board is mounted on a resin circuit board, the characteristics are not deteriorated due to the influence of components arranged around the circuit board. Further, if the antenna is fixed to the upper side 22 of the rear case as much as possible, the antenna can be positioned upward from the substrate ground, so that the relative gain of the antenna is increased.
