Claim 0:
1. A Hall element that detects a magnetic field, the Hall element comprising:
a substrate including a semiconductor region;
a first drive electrode arranged on the substrate;
a first ground electrode arranged on the substrate separately from the first drive electrode in a first direction;
a second ground electrode arranged on the substrate separately from the first drive electrode in a second direction different from the first direction;
wherein the second direction is orthogonal to the first direction;
a second drive electrode arranged on the substrate separately from the first ground electrode in the second direction and separately from the second ground electrode in the first direction;
a first insulation layer formed in a perpendicular direction from a surface of the substrate, wherein
the first insulation layer divides the Hall element into a first region, a second region, a third region, and a fourth region, the first drive electrode is in the first region, the first ground electrode is in the second region, the second ground electrode is in the third region, the second drive electrode is in the fourth region, and
the first insulation layer is located between the first drive electrode and the first ground electrode in the first direction and between the first drive electrode and the second ground electrode in the second direction; and
a detection electrode group including a first electrode group that detects a Hall voltage generated by a first current including components perpendicular to the surface of the substrate, the first current flowing from the first drive electrode to the first ground electrode and the second ground electrode.
