An electronic device includes: a top panel having a manipulation surface; a position detector configured to detect a position of a manipulation input performed on the manipulation surface; a vibrating element; and a drive controlling part configured to drive the vibrating element for generating a natural vibration in an ultrasound frequency band at the manipulation surface such that an intensity of the natural vibration is changed in accordance with the position of the manipulation input performed on the manipulation surface and a time change degree of the position, wherein a width of the vibrating element in a direction in which an amplitude of the natural vibration changes is set based on a ratio between a flexural rigidity of the top panel and a flexural rigidity of the top panel and the vibrating element at a portion where the vibrating element is attached to the top panel.
