Abstract
In some examples, an electric current detection device includes a conductor to which an electric current to be measured is applied, and a circuit unit that has at least a pair of magnetism detection elements for respectively detecting magnetic fluxes generated around the conductor by the electric current. The electric current may be detected based on detection signals obtained from the magnetism detection elements. The magnetism detection elements have a detection sensitivity relative to magnetic fluxes in a parallel orientation. Further, the magnetism detection elements are arranged at positions that are asymmetric positions that avoid a cross-section center of the conductor and that have mutually different distances from the cross-section center. Additionally, the magnetism detection elements are opposed to each other by sandwiching a line that passes through the cross-section center and which is perpendicular to a direction along which the magnetism detection elements are aligned.
