Abstract

A device includes: a communication device case 2 having therein a display panel 13 supported by a support frame 12 and a circuit board 15 stacked with a battery 22 and electrically connected to the battery 22; and an antenna 6 housed in the communication device case 2, the antenna having a first conductor portion 23 formed in a ring, a second conductor portion 24 opposed to the first conductor portion 23 at a predetermined interval, and a third conductor portion 25 for electrically connecting the first conductor portion 23 and the second conductor portion 24. And a communication module assembly 3 is formed by disposing a communication device module in the antenna 6, the communication device module including the circuit board and the support frame. And the first conductor portion 23 of the antenna 6 in the communication device module assembly is positioned on a side of the circuit board 15 opposite to the support frame and outward, and the second conductor portion 24 is positioned on a side of the support frame 12 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. Ther…
