Classification: CPC G  H | IPC G  H

Claim 7:
8. A magnetic sensor comprising:
a first magnetoresistive element whose resistance changes 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 the first magnetoresistive element;
a support member including a top surface and a bottom surface located on a side opposite to the top surface, wherein:
the top surface of the support member includes a curved surface portion curving to protrude in a direction away from the bottom surface of the support member;
the curved surface portion of the top surface of the support member includes a center portion that extends along a first direction and is located at a center of the curved surface portion in a second direction orthogonal to the first direction, and a first side portion and a second side portion that are located on both sides of the center portion in the second direction;
the first side portion and the second side portion are two curved slopes that are located at positions closer to the bottom surface of the support member than the center portion is, and a distance between which increases toward the bottom surface of the support member; and
the first magnetoresistive element is located on the first side portion.
