<p>Provided are a magnetic sensor device, a magnetic encoder device, and a magnetic sensor, whereby mutual magnetic interference between magnetoresistive elements adjacent to each other can be reduced even in the cases where a plurality of magnetoresistive elements are disposed in parallel to each other. Specifically, in the magnetic sensor device and a linear encoder device, a magnetic sensor (20) has disposed therein a plurality of magnetoresistive elements (R1-R4, R11-R14) along the relative moving direction with respect to a magnetic medium (9), and influence of harmonic components is effectively reduced by means of the magnetoresistive elements (R1-R4, R11-R14). A distance (d) between adjacent magnetoresistive elements among the magnetoresistive elements (R1-R4, R11-R14) is equal to or more than a width dimension (w) of the magnetoresistive elements. Consequently, mutual magnetic interference between the adjacent magnetoresistive elements can be reduced.</p> |
