In the mobile telephone, a helical antenna (4) operating as an antenna for television reception is formed by winding a conductive element along the external surface of the case several times at the upper end of the upper case (1). The helical antenna (4) is impedance-matched by a matching circuit (5) in a range of the order from 470 MHz to 700 MHz which is the television broadcast frequency. The matching circuit (5) is connected to a broadcast reception circuit (6). The broadcast reception circuit (6) operates as a reception circuit for receiving the television broadcast wave.
