The present invention suppresses a deterioration of transmission performance and reduces an adverse effect on health of a user, irrespective of the kind of selected antennas. A control section includes antenna selecting section configured so that in a case where a plurality of signals are simultaneously transmitted and where a mobile communication terminal is in a certain use state, the antenna selecting section selects at least one of a first antenna through a fourth antenna so that a distribution range of power densities or of specific absorption rates have no overlapping portion or have an overlapping portion equal to or less than a certain range.
