PROBLEM TO BE SOLVED: To provide a mobile terminal device which enables communication by a mobile unit such as a mobile telephone and non-contact communication simultaneously. SOLUTION: The mobile terminal device 1 comprises a mobile telephone 11 which communicates by a mobile unit such as a mobile telephone, and a non-contact communication part 15 which conducts non-contact communication. The transmission control unit 142 of the mobile telephone 11 has a transmission level control unit 143 which changes the transmission output level of a transmitting part 132. During a period that non-contact communication is conducted by the non-contact communication part 15, while calling or conducting data communication by the mobile telephone 11, the transmission output of the mobile telephone 11 is lowered by a prescribed level by the transmission output level control unit 143. Consequently, mutual interference of the transmitting signal of the mobile telephone and the communication signal of the non-contact communication is reduced, and calling or data communication by the mobile telephone and the non-contact communication are conducted simultaneously.
