Abstract
A position detection device includes a detection portion and a magnetism generation portion. The detection portion includes a first magnetism detection element and a second magnetism detection element. The first magnetism detection element and the second magnetism detection element are disposed on a plane. The magnetism generation portion is disposed at a position opposite the detection portion. The magnetism generation portion includes mutually opposing magnetic fluxes with respect to the detection portion by performing bipolar magnetization on a face opposite the plane where the first magnetism detection element and the second magnetism detection element are disposed.
