Disclosed is a current sensor using a multilayered magnetic core. In one embodiment, the current sensor using the multilayered magnetic core comprising a magnetic core having an air gap between both ends and an opening through which an electric conductor for flowing currents to be measured can pass, and a Hall sensor arranged in the air gap. The magnetic core comprises a plurality of magnetic materials stacked on each other. The hall sensor receives magnetic flux generated by each of the plurality of magnetic materials by the currents for flowing the electric conductor, and measures the currents through a Hall effect from the received magnetic flux. The permeability characteristic of one magnetic substance, hereinafter called as a first magnetic substance, selected from the plurality of magnetic substances has a different characteristic from the permeability characteristic of the other magnetic substance, hereinafter called as a second magnetic substance, selected from the plurality of magnetic substances. |
