Abstract
A magnetic detection apparatus is able to ensure good performance in detecting the position of an detected portion even with a shift or displacement in the position of a magnetoelectric conversion element. The magnetic detection apparatus includes at least one magnetoelectric conversion element disposed to face one of teeth and grooves of a rotating member , a magnet with a direction of magnetization thereof oriented in a direction perpendicular to a radial direction of the rotating member in which the magnet faces the rotating member , and a magnetic guide having a first pole projection and a second pole projection formed in a spaced apart relation with respect to each other in a radial direction of the magnetic moving object in which the magnetic guide faces one of the teeth and the grooves of the rotating member . The at least one magnetoelectric conversion element is disposed between the first and second pole projections when viewed from a direction perpendicular to the radial direction of the magnetic moving object in which the magnetic guide faces one of the teeth and the grooves of the rotating member
