Abstract
A magnetic sensor includes at least one MR element and a coil. The coil includes at least one conductor portion. The at least one conductor portion is each located at a position such that a partial magnetic field generated by the conductor portion is applied to one of the at least one MR element, the one corresponding to the conductor portion, and extends along an imaginary curve curving to protrude in a direction away from the corresponding MR element.
Claims7
A magnetic sensor comprising:
- a first magnetoresistive element and a second magnetoresistive element, resistance of each of the first and second magnetoresistive elements changing with an external magnetic field;
- a coil that generates a coil magnetic field, the coil magnetic field being a magnetic field to be applied to each of the first and second magnetoresistive elements, the coil including a first conductor portion and a second conductor portion;
- and
- a support member that supports the first and second magnetoresistive elements, the support member including a top surface opposed to the first and second magnetoresistive elements and a bottom surface located on a side opposite to the top surface, wherein
- the coil is formed above the top surface of the support member,
- each of the first and second conductor portions is a curved portion that protrudes in a direction away from the first and second magnetoresistive elements and the bottom surface of the support member,
- the first conductor portion is located at a position such that a magnetic field generated by the first conductor portion is applied to the first magnetoresistive element, and
- the second conductor portion is located at a position such that a magnetic field generated by the second conductor portion is applied to the second magnetoresistive element.
