<p>PURPOSE:To dispense with a cut core and thereby to make a device small in size by disposing a magnetoelectric transducer on the one surface side of a flat-plate-shaped conductor and also by connecting the one end side and the other end side of the other surface of the flat-palte-shaped conductor to a current wiring. CONSTITUTION:A current wiring 8 has a construction wherein it is cut between the one end side 6A of a flat-plate-shaped conductor 6 and the other end side 6B thereof. In this case, in other words, the flat-plate-shaped conductor 6 is so constructed as to form a part of the current wiring 8, and a magneto-electric transducer 7 can detect a magnetic field H generated by a current flowing through this flat-plate-shaped conductor 6. Accordingly, a cut core is dispensed with and thereby a device can be made small in size. While the magnetoelectric transducer detects the magnetic field generated by the current flowing through the flat-plate-shaped conductor, in this case, distance between the magnetoelectric transducer and the flat-plate-shaped conductor can be determined when this device is manufactured, and therefore the precision can be attained with ease.</p> |
