Abstract: A current sensor includes a conductor through which a current to be measured flows, and first and second magnetic sensor elements that detect an intensity of a magnetic field generated by the current. The conductor includes first and second flow portions through which the current flows after the current is shunted. The first and second magnetic sensor elements are provided between the first and second flow portions in a thickness direction of the conductor. At least a portion of each of the first and second magnetic sensor elements is provided between the first and second flow portions in a width direction of the conductor. In the width direction of the conductor, a distance between a center portion of the first magnetic sensor element and a center portion of the second magnetic sensor element is less than or equal to a distance between the first flow portion and the second flow portion.
