In a mobile terminal of the present invention, when the finger of a user is approaching a touch panel, an estimation coordinate as a position of the finger and an estimation distance as a distance between the finger and the touch panel are determined based on a capacitance value between the finger and the touch panel, and capacitance distribution data showing a distribution of the capacitance values is generated. When the capacitance distribution data is similar to set capacitance distribution data, an object icon, which is arranged in the estimation coordinate, of a plurality of icons displayed on the touch panel is displayed on the touch panel in a size larger than in a basic size. In this way, only when detecting that the finger of the user is approaching the touch panel, the icon which is displayed on the touch panel is displayed in an expansion state. Therefore, a malfunction can be prevented and the improvement of operability can be attempted to the user.
