An input device comprising: an operation part, wherein the operation part includes an operation panel member, wherein the operation panel member has a touch surface and is configured to detect coordinates of a touched position within the touch surface; an actuator configured to impart a tactile effect to the operation part; and a controller configured to apply, to the actuator, a control signal for starting to apply a first vibration to the operation part at a first timing and for starting to apply a second vibration to the operation part at a second timing after the first timing, such that a combined vibration of the first vibration and the second vibration is applied to the operation part, wherein the control signal comprises a voltage rising at the first timing and falling at the second timing,wherein the first vibration and the second vibration are at a resonance frequency of the input device and are independent of each other, characterized in that the controller is configured to change the combined vibration to two or more different combined vibrations by changing a control period of time that extends from the first timing to the second timing to two or more different control periods of time, wherein the controller is configured to change the control period of time such that each of the two or more different control periods of time is less than or equal to one half of a period of the first vibration, and wherein the controller is configured to select the control period of time in accordance with the coordinates of the touched position and an input mode, the input mode being set in accordance with an operation in an automobile. an operation part, wherein the operation part includes an operation panel member, wherein the operation panel member has a touch surface and is configured to detect coordinates of a touched position within the touch surface; an actuator configured to impart a tactile effect to the operation part; and a controller configured to apply, to the actuator, a control signal for starting to apply a first vibration to the operation part at a first timing and for starting to apply a second vibration to the operation part at a second timing after the first timing, such that a combined vibration of the first vibration and the second vibration is applied to the operation part, wherein the control signal comprises a voltage rising at the first timing and falling at the second timing,wherein the first vibration and the second vibration are at a resonance frequency of the input device and are independent of each other, characterized in that the controller is configured to change the combined vibration to two or more different combined vibrations by changing a control period of time that extends from the first timing to the second timing to two or more different control periods of time, wherein the controller is configured to change the control period of time such that each of the two or more different control periods of time is less than or equal to one half of a period of the first vibration, and wherein the controller is configured to select the control period of time in accordance with the coordinates of the touched position and an input mode, the input mode being set in accordance with an operation in an automobile.
