An operation device includes a movable part having an operating surface on which a contact operation is performed by an living body, a vibration exciter attached to the movable part at a position other than the operating surface, and configured to excite the movable part in a first direction along the operating surface, and in a second direction intersecting the operating surface, a base part, and an elastic support, provided between the movable part and the base part, and configured to elastically support the movable part with respect to the base part. The movable part provides a tactile sensation to the living body making the contact operation when excited in the first direction by the vibration exciter, and generates a sound from the operating surface when excited in the second direction by the vibration exciter.
