A magnetic sensor device includes: a magnetic field generator, disposed at one surface side of a sheet-like to-be-detected object including a magnetic component, to generate an intersecting magnetic field intersecting the object; and a magnetoresistive effect element disposed between the object and the magnetic field generator, having a resistance value changing in accordance with change of a component of the intersecting magnetic field in a conveyance direction along which the object is conveyed, when the object is conveyed. The magnetoresistive effect element includes resistive elements adjacent to each other in the conveyance direction and interconnected by a bridge, disposed in linear symmetry relative to an axis perpendicular to the conveyance direction and extending through a center of the bridge. A position in the conveyance direction of the bridge center of the magnetoresistive effect element coincides with a position in the conveyance direction of the magnetic field generator center.

Magnetic sensor device

A magnetic sensor device includes: a magnet; yokes arranged on the magnet; and a magnetoresistance effect element to which is applied a leakage magnetic field emitted from the yokes to an exterior thereof. A detection region of the magnetoresistance effect element is at the side opposite to the magnet. The magnetoresistance effect element detects a change of a bias magnetic field of the magnetoresistance effect element that occurs when the object to be detected including the hard magnetic material passes through the detection region. The magnetic sensor device can accurately detect an object to be detected using a hard magnetic material.

A magnetic circuit, provided with a short magnet () and short magnet () that are arranged in an array, and a yoke () and a yoke () provided so as to sandwich the short magnet () and short magnet (). The short magnet () and short magnet (), are arranged, that have a space between them that is a predetermined gap () or less in the arrangement direction of the array respectively. In addition, the short magnet () and short magnet () are arranged so that one magnetic pole is located on the side toward one of the pair of yokes () and (), and the other magnetic pole is located on the side toward the other yoke.
