PROBLEM TO BE SOLVED: To provide an electric current detection structure capable of accurately detecting electric current flowing in a bus bar.SOLUTION: An electric current detection structure includes a magnetic detection element 3 that is provided in a connection part between two bus bars 2 for flowing electric current in longitudinal directions and measures the intensity of a magnetic field generated by electric current flowing in both the bus bars 2. The two bus bars 2 are arranged so as to: allow their longitudinal directions to conform with each other; allow their ends to overlap with each other in the connection part 4; and be displaced in width directions. The magnetic detection element 3 is arranged near the connection part 4 so as to allow its detection axis D to be in a longitudinal direction of the bus bar 2. |
