MAGNETIC SENSOR

摘要

Each of a plurality of first magnetoresistive elements includes a double spiral pattern in plan view. The double spiral pattern includes a first spiral pattern, a second spiral pattern, and an S-shaped or inverted S-shaped pattern that joins the first spiral pattern and the second spiral pattern at a center portion of the double spiral pattern. Orientations of the double spiral patterns of the plurality of first magnetoresistive elements are different from each other in a circumferential direction, and orientations of the S-shaped or inverted S-shaped patterns differ from each other in the circumferential direction.

1. A magnetic sensor comprising:
a plurality of magnetoresistive elements electrically connected to each other to provide a bridge circuit; wherein the plurality of magnetoresistive elements includes a plurality of first magnetoresistive elements and a plurality of second magnetoresistive elements; a resistance change rate of each of the plurality of first magnetoresistive elements is greater than a resistance change rate of each of the plurality of second magnetoresistive elements; each of the plurality of first magnetoresistive elements includes a double spiral pattern in plan view; the double spiral pattern includes a first spiral pattern, a second spiral pattern, and an S-shaped or inverted S-shaped pattern that joins the first spiral pattern and the second spiral pattern at a center portion of the double spiral pattern; and orientations of the double spiral patterns of the plurality of first magnetoresistive elements differ from each other in a circumferential direction, and orientations of the S-shaped or inverted S-shaped patterns differ from each other in the circumferential direction.
