Abstract
When a through hole is formed in a primary conductor, a measurement target current partially becomes a bypass current that flows around the through hole. Only a magnetic field component in the X-axis direction is generated from the current that flows through a portion without the influence of the through hole. However, the bypass current generates a magnetic field component in the Y-axis direction at the tilt portion. A magnetic detection element having a magnetic field detection sensitivity only in the Y-axis direction is installed near the through hole such that the magnetic field detection direction is set in the Y-axis direction, thereby detecting the magnetic field component and measuring the current amount without the influence of a neighboring current.
