PROBLEM TO BE SOLVED: To provide a current sensor capable of being miniaturized while maintaining insulation resistance.SOLUTION: A plurality of terminals 9 is arranged along a first short side 5a of an insulation base plate 5, and a current path 1 is bent in a U shape. Both end parts 1a of the current pass 1 abut against both long sides 5c facing the insulation base plate 5, and one side face of each end part 1a of the current path 1 is arranged so as to be positioned in the vicinity of a second short side 5b facing the first short side 5a. A magnetic field control plate 3 is bent in a U shape, and a first end part 3a of the magnetic field control plate 3 is arranged so as to abut against the second short side 5b. An orthogonal part 1c in which the current path 1 and the magnetic field control plate 3 are orthogonal to each other in a plan view is formed in the current path 1. A magnetic sensor element 7a is arranged at a center point of the opening width of the magnetic field control plate 3, and the center point of the orthogonal part 1c is arranged at a position facing the magnetic sensor element 7a, and the center point of a width direction of the end part 1a of the current path 1 is at the side of the second short side 5b of the center point of the width direction of the orthogonal part 1c.SELECTED DRAWING: Figure 1 |
