PROBLEM TO BE SOLVED: To provide a current sensing structure which enables accurate detection of a magnetic field and thus allows for accurately sensing current flowing through bus bars even when a GMR element is used as a magnetic sensing element.SOLUTION: A current sensing structure comprises a first bus bar 2 through which current flows, a second bus bar 3 through which current flows in the same direction as the current flowing through the first bus bar 2, and a magnetic sensing element 4 located between the first bus bar 2 and the second bus bar 3. The magnetic sensing element 4 is positioned to be able to measure intensity of a magnetic field in a direction that is perpendicular to the direction of the current flowing through the bus bars 2, 3 and is also perpendicular to a direction in which the first bus bar 2 and second bus bar 3 are arrayed. |
