PROBLEM TO BE SOLVED: To provide a mobile telephone device and a built-in antenna thereof, which are capable of reducing a space for mounting without lowering antenna performance, assembling without soldering processing, and reducing the number of parts. SOLUTION: A casing comprises a rear case 2 and a front case 3. A built-in antenna 10 is arranged in a predetermined space in the rear case 2. The whole of the built-in antenna 10 is held being inserted between a PCB 6 and the rear case 2. One end of an antenna metal fitting 14 is connected to the power supply part of the built-in antenna 10, and the other end is extended to a predetermined pattern of the PCB 6. The metal fitting is electrically connected to the power supply part on the PCB 6 using a contact pressure obtained by holding the antenna being inserted. Therefore, soldering is not required for connecting the antenna metal fitting 14 and the power supply part on the PCB 6. COPYRIGHT: (C)2007,JPO&INPIT
