The current sensor has at least one magnetic field sensor for measuring a current in a conductor by determining the strength of the magnetic field produced by the current. Furthermore, the current sensor has an arrangement for focussing and guiding the magnetic field toward the magnetic field sensor. The arrangement has at least two mutually opposite sections, between which the magnetic field sensor is arranged. The arrangement is composed of a magnetic material which has a coercivity strength of less than 10 A/cm.
