Abstract
A magnetic sensor device () includes a magnetic sensor unit including a magnetoresistive element mounted on a sensor board extending in a longitudinal direction and a magnet () located on a surface of the sensor board opposite to a surface on which the magnetoresistive element is mounted, a housing supporting the magnetic sensor unit, a magnetic shield unit () covering side surfaces and a bottom surface of the housing, and a cover covering an upper portion of the housing. The magnetic shield unit () has an opening () facing in Z-axis direction from the magnetoresistive element toward a transport path of a sensing target. The opening () is defined by two long sides in the longitudinal direction and two short sides in a lateral direction. The two long sides of the magnetic shield unit () are nearer to the sensing target in Z-axis direction than the two short sides.
