COMMUNICATION TERMINAL DEVICE

PROBLEM TO BE SOLVED: To provide a communication terminal device which can provide a means which does not break characteristics of a radio wave without increasing a size of a case, does not damage the case, can be operated simply by one hand, enhances a man-machine interface, and extends a function of the communication terminal device such as a cellphone, PHS and PDA. SOLUTION: In the communication terminal device, a first case 11 provided with a liquid crystal display screen 10 (display part) for displaying various pieces of information on a display screen is connected to a second case 12 provided with an input 9 in which a user operates to press a button 9a, thereby enabling a desired input to be operated. Aside from the input 9, the communication terminal device comprises a pressing button 4 which is actuated to the longitudinal one side of the second case (any one of the cases) 12 by the user's pressing operation, to extend a function of the input 9.
