An input device includes a substrate, a key top, a magnet, magnetic sensors, and electromagnetic converters. The substrate includes first and second surfaces. The key top is arranged on a first surface side, slides from a reference position in directions parallel to the substrate, and moves in a perpendicular direction. The magnet is fixed on a substrate side, and moves together with the key top. The magnetic sensors are fixed on the second surface, are respectively arranged apart in different directions parallel to the substrate, and detect a position of the magnet. The electromagnetic converters are fixed on the second surface, are respectively arranged apart in different directions parallel to the substrate, are arranged at positions different from the magnetic sensors, and generate magnetic force in a direction in which the magnet is away from the substrate in the perpendicular direction, in accordance with a supply of electrical power.
