PROBLEM TO BE SOLVED: To solve the problem that, if the heat radiation performance of a magnetometric sensor and a signal processing device is poor, the temperature becomes significantly different between the magnetometric sensor and the signal processing device when heat is generated in a current path, etc., resulting in the accuracy of detecting a current becoming degraded.SOLUTION: A current sensor according to the present invention comprises a first and a second magnetometric sensor for detecting magnetism, a current path wired in a first circumferential direction around the first magnetometric sensor and wired in a second circumferential direction opposite the first circumferential direction around the second magnetometric sensor, and a signal processing device for processing output signals from the first and second magnetometric sensors, the first and second magnetometric sensors and the signal processing device being disposed on a metal plate. |
