A device includes: a communication device case,having therein a display panel,supported by a support frame,and a circuit board,stacked with a battery,and electrically connected to the battery,and an antenna,housed in the communication device case,the antenna having a first conductor portion,formed in a ring, a second conductor portion,opposed to the first conductor portion,at a predetermined interval, and a third conductor portion,for electrically connecting the first conductor portion,and the second conductor portion,And a communication module assembly,is formed by disposing a communication device module in the antenna,the communication device module including the circuit board and the support frame. And the first conductor portion,of the antenna,in the communication device module assembly is positioned on a side of the circuit board,opposite to the support frame and outward, and the second conductor portion,is positioned on a side of the support frame,opposite to the circuit board and outward. As a result, the conductor portion of the antenna is positioned in an outermost portion of the communication device module. Therefore, the dimension of strap in the thickness direction and the dimension of the communication device case in the plane direction can be set to small values, respectively. In addition, favorable feeling of wearing the communication device can be obtained, and the size of the communication device as a whole can be made small.
