PROBLEM TO BE SOLVED: To provide a constitution in a mobile terminal equipped with input keys circularly arranged with button members, in which independency of each button member can be secured easily, and gaps between button members can be closed superbly. SOLUTION: The mobile terminal 1 includes an exterior case 2 and a cross key 10 exposed from this exterior case 2. The cross key 10 is equipped with 4 button members 11 to 14 which are displaceably constituted respectively in a form exposed from the exterior case 2. Moreover, these button members 11 to 14 are arranged in a circular state surrounding a prescribed center position P1, and an elastic part 20 which is elastically deformable is installed to couple the button members neighboring each other in the circumferential direction. This is constituted so that by this elastic part 20 the gaps between the neighboring button members are respectively closed, and the elastic part 20 becomes flexibly deformed when respective button members 11 to 14 are press-operated, and that respective button members become displaced independently from other button members.
