Abstract
A magnetic sensor device includes: a magnet, extending in a longitudinal direction, that has different magnetic poles in a direction perpendicular to a conveyance direction of a detected object having a magnetic material, the longitudinal direction being orthogonal to the conveyance direction; and anisotropic magnetoresistive elements arranged linearly in the longitudinal direction on a detected object-side magnetic pole of the magnet, wherein the magnet is provided with a magnetic material yoke between the anisotropic magnetoresistive elements and the magnet, and the end of the magnet in the longitudinal direction has a greater length in the direction perpendicular to the conveyance direction than the center in the longitudinal direction.
