An input device and an input module are provided that vibrate in a direction along the surface of a cantilevered operation unit. The input device includes a fixed member rotatably supporting a rotation shaft, an operation unit having an end rotatably supported by the rotation shaft and being rotatable relative to the fixed member, and a vibrating element that generates vibration of the operation unit in the axial direction of the rotation shaft in response to a rotation operation performed on the operation unit.
