The vibrating device is provided with two support units, a vibrating plate, a vibrating element (for example, a piezoelectric element), and a spindle. The two support elements are respectively provided to two positions that differ from each other in the lengthwise direction. The two ends of the vibrating plate in the lengthwise direction are respectively supported by the two support elements. The vibrating element is attached to the center portion in the lengthwise direction of the bottom surface of the vibrating plate. The spindle has: two free ends respectively positioned at the two ends in the lengthwise direction; and an affixed section positioned between the free ends. The affixed section is affixed to the top surface of the vibrating plate. When the vibrating element is not being driven, the free ends are each spaced from the top surface of the vibrating plate.
