Abstract
An input apparatus (for example, a mobile terminal apparatus ()) includes a display unit () that displays a plurality of operation position displays (for example, operation position displays (to)); and a detection unit that contactlessly detects an operation which corresponds to an operation position set in a specific space of a front of the input apparatus in correspondence to each of the plurality of operation position displays. The detection unit includes a first piezoelectric element (an oscillation piezoelectric element ()) that oscillates ultrasound toward the front space of the input apparatus; a second piezoelectric element (a reception piezoelectric element ()) that detects the ultrasound which is oscillated by the first piezoelectric element; and a determination unit that determines whether or not an operation is performed on a certain operation position based on a result of detection performed by the second piezoelectric element.
