An input device with a hollow portion therein at a neutral position includes a return member capable of self-returning to the neutral position upon deformation, a magnetic member movable in three mutually-orthogonal axial directions accompanied with the deformation of the return member, and a plurality of magnetic sensors individually detecting the position of the magnetic member in the three axial directions with respect to the neutral position. The three-dimensional operation of the magnetic member may be easily detected by a simplified structure and the magnetic member is located with high accuracy.
