Abstract
Provided is a displacement detection device which reduces the influence of disturbance noise on a magnetic field to be detected and makes a range detectable by a monopole magnet wider than a pitch of a magnetic detection elements. A displacement detection device includes a magnet which is displaced in a displacement direction D, is rod-shaped and has a form in which a longitudinal direction and the displacement direction Dform a predetermined angle θ, and a sensor IC in which magnetic detection element groups, which detect a magnetic flux density of a magnetic field formed by the magnet in an x direction and a z direction orthogonal to the displacement direction D, are arranged in pairs with a predetermined interval d, and which outputs a difference between outputs of the magnetic detection element groups.
