PROBLEM TO BE SOLVED: To provide a current sensor capable of applying a magnetic field larger than that of a conventional case to a magneto-sensitive element as long as measured currents are equal in magnitude.SOLUTION: A current conductive part 10 includes a plurality of internal penetration parts 11 penetrating a virtual plane inside first and second magnetic bodies 30A and 30B, and a plurality of external penetration parts 12 penetrating the virtual plane outside the first and second magnetic bodies 30A and 30B. The plurality of internal penetration parts 11 and the plurality of external penetration parts 12 are included in one common current path. The penetration directions of current flowing through the plurality of internal penetration parts 11 through the virtual plane are the same, the penetration directions of current flowing through the plurality of external penetration parts 12 through the virtual plane are the same, and the current flowing through the internal penetration part 11 and the external penetration part 12 are reverse in penetration direction through the virtual plane. Magnetic fields generated with current flowing through the plurality of internal penetration parts 11 reinforce each other at the presence position (magneto-sensitive position) of a Hall IC 20 to be applied to the Hall IC 20. |
