PROBLEM TO BE SOLVED: To provide a mobile terminal that can feed power to an antenna with a simple configuration and enhance the SAR(Specific Absorption Rate) affected on human bodies in the case of using a dipole antenna for a built-in antenna. SOLUTION: A feeding circuit 7 and a primary radiation element 8 are provided to a PCB 1 of a mobile telephone set and transmission power from a transmission reception circuit section 4 is fed to the primary radiation element 8 via the feeding circuit 7 through a coaxial cable 5. The mobile phone is provided with a dipole antenna 10 that is placed on an outer wall or an inner wall of a case 9 of the mobile telephone set or imbedded therein opposite to the primary radiation element 8 with space inbetween. Furthermore, a speaker 6 is mounted on a side (toward the head of a user) opposite to a side on which the primary radiation element 8 of the PCB 1 is placed. Thus, the primary radiation element 8 and the dipole antenna 10 are apart from each other mechanically but capacitively or magnetically coupled electrically then no feeder is required. Moreover, the PCB 1 shades a radio wave emitted from the antenna to the head of the user.
