Abstract:
An input device includes a first yoke; a substrate disposed on the first yoke; a coil disposed on the substrate; and a second yoke disposed above the coil and configured to be displaced downward by a force applied and thereby to change inductance of the coil. The input device is configured to output a signal corresponding to the amount of displacement of the second yoke. The substrate has an opening that communicates with a hollow of the coil, and the first yoke includes a step that is inserted into the opening of the substrate.
