In order to transmit radio waves even when an external device is connected, a mobile phone includes an antenna; an FM transmitter which outputs signals for transmitting radio waves from the antenna; an earphone terminal 17, a USB terminal 18, and a charging terminal to each of which an external device may be connected; and a connection detecting portion which detects whether an external device is connected to any of the earphone terminal, the USB terminal, and the charging terminal. The FM transmitter controls transmission power of the radio waves (S05, S06) in accordance with a status of connection with an external device (YES or NO in S02) which is detected by the connection detecting portion. |
