PROBLEM TO BE SOLVED: To provide a current sensor that allows a relatively simple configuration to detect a current.SOLUTION: A current sensor 1 is configured to cause a current flowing to a busbar 9 to generate a magnetic field inside a feedback core 3; detect a magnetic flux in this instance by a flux gate sensor 60 (magnetic field sensor 6) retained to a probe coil bobbin 7; supply a current corresponding to a detection result by the magnetic filed sensor 6 to a feedback coil 4; and detect the current flowing to the busbar 9 by a current value supplied to the feedback coil 4 at a point of time when cancelling out the generated magnetic filed by the current flowing to the busbar 9. The feedback coil 4 is configured to be positioned by a second plate part 72, a fourth plate part 75, a first end part 716, a second end part 717 of the probe coil bobbin 7, and the like. |
