<p>A current sensor is provided with a busbar (110) through which current under measurement flows and at least one magnetic sensor for detecting the strength of a magnetic field generated by the current flowing through the busbar (110). The busbar (110) includes a first busbar part (111) and a second busbar part (112) that are electrically connected in series. The first busbar part (111) extends so as to surround the second busbar part (112) with an interval therebetween. The magnetic sensor is disposed between the first busbar part (111) and the second busbar part (112) so as to be capable of detecting a magnetic field in a direction perpendicular to the direction of the extension of the second busbar part (112).</p> |
