Abstract
A current sensor includes two bus bars, each of which is formed in a plate shape, the two bus bars being aligned and arranged so as to be spaced apart from each other in a plate width direction thereof, and magnetic detection element arranged opposite the two bus bars, respectively, in a plate thickness direction of the bus bars to detect a magnetic field strength generated by a current flowing through the corresponding bus bars. The magnetic detection element are gradient detection type magnetic detection elements that output a difference between magnetic field strengths detected at two magnetic sensing positions, respectively, and are arranged in such a manner that a detection axis direction thereof is perpendicular to a length direction of the bus bars and is tilted with respect to the plate thickness direction.
