Abstract
A current sensor includes: a current path; a semiconductor substrate; and a Hall element on the substrate. The Hall element detects a magnetic flux in a magnetic field caused by a detection object current. The Hall element generates a Hall voltage corresponding to the magnetic flux when a driving current flowing in a direction perpendicular to the semiconductor substrate is supplied to the Hall element, and when the magnetic flux having a component parallel to the semiconductor substrate affects the Hall element. The current path is disposed on the semiconductor substrate. The current path is electrically isolated from the Hall element.
