PROBLEM TO BE SOLVED: To provide current detection structure which can use a highly sensitive magnetic detection element even when a large current flows in a bus bar, and can detect a current with high accuracy as a result.SOLUTION: The current detection structure is provided which includes a bus bar 2 and a magnetic detection element 3 for measuring the intensity of a magnetic field generated by a current flowing in the bus bar 2. The current detection structure is constituted in such a way that: a part of the bus bar 2 is bent in the thickness direction to form a horizontal section 2a and an inclined section 2b inclined in the thickness direction relative to the horizontal section 2a; the magnetic detection element 3 is disposed near the inclined section 2b in such a way that its detection axis D is along the longitudinal direction of the horizontal section 2a; and the magnetic detection element 3 detects the intensity of a magnetic field which is in a direction along the longitudinal direction of the horizontal section 2a, among magnetic fields generated by a current flowing in the inclined section 2a. |
