An input device comprising:

• an operation unit on which an input operation is performed by the contact between an operating body and an upper surface of the operation unit or the approach of the operating body to the upper surface of the operation unit, and which is supported so as to move downward from a reference position according to pressing performed by the operating body and is formed in the shape of a flat plate;
• an input detection unit configured to detect the input operation performed on the operation unit;
• a pressing detection unit configured to detect that the operation unit has been moved downward from the reference position;
• a drive member that is provided below the operation unit and drives the operation unit in a vertical direction;
• and
• a case member configured to hold the drive member,
• wherein the drive member is disposed at a central position of the operation unit in plan view,
• the drive member is a solenoid actuator including a columnar plunger that is driven in the vertical direction,
• an upper end portion of the plunger is disposed so as to come into contact with a lower surface of the operation unit, and
• the plunger is pressed down by the operation unit with a downward movement of the operation unit.
