Claim 8:
9. An electronic component, comprising:
a Hall element formed on a substrate including a semiconductor region; and
a control circuit that detects a magnetic field acting on the Hall element,
the Hall element including
a first electrode,
a second electrode arranged separately from the first electrode in a first direction,
a third electrode arranged separately from the first electrode in a second direction,
wherein the second direction is orthogonal to the first direction,

a fourth electrode arranged separately from the second electrode in the second direction and arranged separately from the third 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 is located between the first electrode and the second electrode in the first direction and between the first electrode and the third electrode in the second direction that is orthogonal to the first direction, and

a detection electrode group, wherein
the detection electrode group
detects a Hall voltage generated in a first state in which a first current including components perpendicular to the surface of the substrate flows from the first electrode to the second electrode and the third electrode and in which a second current including components perpendicular to the surface of the substrate flows from the fourth electrode to the second electrode and the third electrode, and
detects a Hall voltage generated in a second state in which a third current including components perpendicular to the surface of the substrate flows from the second electrode to the first electrode and the fourth electrode and in which a fourth current including components perpendicular to the surface of the substrate flows from the third electrode to the first electrode and the fourth electrode, and

the control circuit detects the magnetic field acting on the Hall element, based on a difference between the Hall voltage detected in the first state and the Hall voltage detected in the second state.
