<p>PURPOSE: To provide a current detector which is reduced in size and price by simplifying its structure and, at the same time, can stably perform detecting operations. CONSTITUTION: In the current detector, a Hall element 2 is positioned near a coil section 1 constituted by incorporating a magnetic material 6 in the section 1 so that the element 2 can detect magnetic fluxes generated by the coil current of the coil section 1 and a detection circuit 4 can detect the flow of the electric current based on the output of the element 2. A substrate 3 mounting the Hall element 2 is mounted on a control circuit board 5 together with the detection circuit 4 and the coil section 1 in which the substrate 3 can be positioned is mounted on the circuit board 5 so that the Hall element 2 can detect the magnetic flux.</p> |
