The connection portion 322 of the first FPC antenna 32 is located at a position near the circuit board 20 on the inner side wall 11c of the frame portion 11.

Since the frame portion 11 beside the battery 60 is not provided with the holder in the first embodiment at too many positions, the recess 11a is provided on the stepped surface 115 without affecting the position of the battery 60. In addition, since the circuit board 20 is not disposed at the position of the battery 60, the space of the frame portion 11 beside the battery 60 is often wasted, and in this embodiment, the groove 11a is disposed on the step surface 115 of the frame wall beside the battery 60, and the first bracket 31, the radiation portion 321 of the first FPC antenna 32, and the first bracket 31 are completely disposed in the groove 11a, so that the space utilization of the frame portion 11 beside the battery 60 can be effectively improved, and the design of the waist antenna beside the battery 60 can be realized.
