Abstract
In a piezoelectric oscillation device in which a support substrate is oscillated using a bimorph-type piezoelectric oscillation element, the click sensation when the support substrate is operated is improved, and shock resistance of a control panel is improved. Provided is a piezoelectric oscillation device in which wiring is not easily broken. On the rear side of a touch panel (), one main surface of a bimorph-type piezoelectric oscillation element () is entirely bonded via an elastic body () having a tensile elasticity of 20-100 MPa as measured according to JIS K7161. The piezoelectric oscillation element () has surface electrode layers (A,B) connected to terminal electrodes (A,B) via wiring lines (A,B). The wiring lines (A,B) are formed on top of a wiring protection layer () made of an elastic body provided on the rear side of the touch panel (), and because the wiring lines can move following the displacement and are therefore resistant to breakage. When the piezoelectric oscillation element () is displaced toward the touch panel (), it can transmit a greater amount of displacement to the touch panel () than when it is displaced to the opposite side.
