Abstract
A tactile sense presenting device that includes a piezoelectric film, a first diaphragm and a second diaphragm. The piezoelectric film deforms in a planar direction when a voltage is applied thereto. The first diaphragm and the second diaphragm sandwich the piezoelectric film. Opposed ends of the first diaphragm and opposed ends of the second diaphragm are fixed, respectively, to opposed ends of the piezoelectric film such that the first diaphragm and the second diaphragm are in a warped state.
