PROBLEM TO BE SOLVED: To provide a current sensor that allows for stable sensing and that is insensitive to disturbances.SOLUTION: In a current sensor, a bus bar 80 is sandwiched between a first circuit substrate 20 and a second circuit substrate 30 in a state where magnetoelectric conversion element mounting surfaces 21 and 31 face each other, and in a state where surfaces formed by both long sides of a rectangular cross-section of the bus bar 80 face a first magnetoelectric conversion element mounting surface 21 of the first circuit substrate 20 and a second magnetoelectric conversion element mounting surface 31 of the second circuit substrate 30, respectively. A first Hall IC 40 is mounted on the first magnetoelectric conversion element mounting surface 21 of the first circuit substrate 20, and outputs a signal corresponding to measured current flowing through the bus bar 80. A second Hall IC 50 is mounted on a second magnetoelectric conversion element mounting surface 31 of the second circuit substrate 30, and outputs a signal corresponding to the measured current flowing through the bus bar 80. |
