PROBLEM TO BE SOLVED: To provide a current sensor which is capable of reducing effect of neighboring current paths.SOLUTION: A plurality of current paths (11, 12 and 13) arranged in an identical plane comprise first conductor parts (11a, 12a and 13a), second conductor parts (11b, 12b and 13b) connected to one side ends of the first conductor parts, and third conductor parts (11c, 12c and 13c) connected to the other side ends of the first conductor parts. On an extention line extending in the longitudinal direction of the first conductor part (12a) from the one end of the first conductor part (12a), the neighboring second conductor part (11b) is disposed, and on an extention line extending in the longitudinal direction of the first conductor part (12a) from the other end of the first conductor part (12a), the neighboring third conductor part (13c) is disposed. A pair of magnetoelectric transducers are disposed in positions which sandwich the first conductor part (12a) symmetrically and are vertical to the plane, and detect a magnetic field generated by the first conductor part (12a). |
