Abstract
A current detection apparatus where a sensor unit that detects the magnetic field in a predetermined magnetic field detection direction is disposed in a vicinity such that the magnetic field detection direction is substantially orthogonal to an extension direction of the subject bus bar at the detection portion, one of the plurality of bus bars disposed adjacent to the subject bus bar is set as an adjacent bus bar, a plane that is orthogonal to an extension direction of each portion of the adjacent bus bar is set as an extension orthogonal plane of the portion, and the extension direction of each portion of the adjacent bus bar relative to the sensor unit is set such that none of the extension orthogonal planes of the respective portions of the adjacent bus bar pass through the sensor unit in a parallel direction to the magnetic field detection direction.
