A mobile terminal includes a battery; a power supply block which supplies power of the battery; and a radio communication block which communicates with a base station when the power is supplied from the battery through the power supply block. The mobile terminal further includes a first switch which is interposed between the power supply block and the radio communication block; and a key operation section to which the power is always supplied from the battery through the power supply block. A control unit controls the first switch to stop the power supply from the battery to the radio communication block in response to a manual operation of the key operation section.
