PROBLEM TO BE SOLVED: To provide a case structure in which a rigidity of a small mobile terminal is maintained, while being made thinner. SOLUTION: The case body 101 is provided with a plurality of concave portions 111. On a switch button sheet 102A, there are formed wiring patterns 122A, 122B. On a cover sheet, there is arranged a current collector 123 which is elastically deformable. The current collector is pressed down by the cover sheet and its outer circumferential portion contacts with the wiring pattern 102A. When the switch button 125 is pressed down, the switch button sheet, the cover sheet and the current collector are deformed elastically, and the wiring pattern 122B is pushed downward and contacts with the current collector, and both of the wiring patterns are connected electrically. A projection 112 makes certain that the connection (contact) and a sense of clear clicking can be given. Since the case has no penetration hole, rigidity can be maintained; and since independent space for fixing a switch becomes unnecessary, its thickness can be made smaller.
