An input device includes an operation panel member with an operation surface; a support member contacting a side face of the operation panel member to support the operation panel member, the side face being perpendicular to the operation surface of the operation panel member; and an actuator configured to vibrate the support member in a direction parallel to the operation surface. The support member contacts the operation panel member only at the side face, and the operation panel member vibrates in a direction parallel to the operation surface by transmission of a vibration of the support member from the side face to the operation panel member.
