Abstract
An input device includes a first operating element and a first sensor. The first sensor includes a first conductor, a first coil, and a first magnetic material forming an open magnetic circuit together with the first coil. A positional relationship between the first coil and the first magnetic material is fixed. A first distance between a first end portion of the first magnetic material and the first conductor varies according to the amount of operation on the first operating element. The first sensor outputs a first signal corresponding to the first distance.
