PROBLEM TO BE SOLVED: To enable an administrator to limit the range of use of communication terminal in detail so as to prevent a person to be supervised such as a child from using the communication terminal in excess of the range intended by the administrator. SOLUTION: A storage section 12 is provided with: a password storage area 12-1 for storing a password being authentication information; a limit information storage area 12-2 for storing control information used to control an operation of a mobile phone 1; and a permission list 12-3 for registering information not limited by the administrator even when the control information in the limit information storage area 12-2 is effective. When an authentication section 11-1 of a control section 11 discriminates coincidence for the authentication of an entered password, a setting state of the limit information storage area 12-2 can be revised to limit the range of use of the mobile phone 1 by the person to be supervised into the range intended by the administrator.
