Abstract
A magnetic position detection apparatus includes a substrate, a magnet, a bridge circuit including first through fourth magneto-electric converting elements formed on the substrate, and a detection circuit. A substrate surface is substantially perpendicular to a magnet magnetization direction. The second and third magneto-electric converting elements are, when viewed along the magnet magnetization direction, disposed to be on or in the vicinity of a straight line passing through a center point of a magnetic pole of the magnet and parallel to a straight line perpendicular to both the magnet magnetization direction and the magnetic mobile object. The first and fourth magneto-electric converting elements are disposed so that, when not opposed to the magnetic mobile object, a component of a substrate of a magnetic field to be applied thereto is substantially same as that of a magnetic field to be applied to the second and third magneto-electric converting elements.
