A magnetic sensor device may include a magnetic sensor element structured to detect a magnetic property of a medium. The magnetic sensor element may include a sensor core having a body part and one or a plurality of protruded part(s) which is protruded from the body part, an exciting coil which is wound around the sensor core, and a detection coil which is wound around the sensor core. The body part and the protruded part of the sensor core forms an open magnetic path, and a stepped part is formed on a side face of at least one piece of the protruded part. |
