PROBLEM TO BE SOLVED: To obtain the portable telephone set that is small in size and light in weight without deteriorating the shield performance and the performance of a reception exclusive antenna. SOLUTION: Since a reception exclusive antenna 9 is mounted on an outer face of a rear case 6 in a way of feeding to a radio circuit section 2, and a conductor layer 8 is provided to an inner face of the rear case 6, it is not required to provide a hole for preventing characteristic deterioration of the reception exclusive antenna 9 for the rear case 6 and the conductive layer 8 so as to effectively suppress electromagnetic interference between a whip antenna 5 and a radio circuit section 2. Thus, it is not required to provide separately a shield box and the portable telephone set is made small and light. |
