PROBLEM TO BE SOLVED: To provide a portable terminal device in which a main display is prevented from being deformed or destroyed by force applied to a sub display which is located on the outer surface, in a state where the case is folded. SOLUTION: The bottom portion of a sub display holder 4 is shallowly tapered. Thus, when a portable terminal device is depressed, stress to a main display 15 concentrated on the bottom portion of the sub display holder 4 is dispersed and the main display 15 is protected from deformation or destruction. Furthermore, the corners of the bottom portion of the sub display holder are shaped into R-forms. Consequently, during depressing, the stress to the main display 15 due to the corners of the bottom portion of the sub display holder 4 is dispersed, and the main display 15 is protected from deformation breakdown.
