<p><P>PROBLEM TO BE SOLVED: To provide a current detector capable of being relatively inexpensively manufactured and saving resources. <P>SOLUTION: A plurality of C-shaped metal sheets 3a, 3a... thin in width are integrally aligned in a direction parallel with a current path 2 to form a magnetic material 3. It is not therefore required to process thick and wide metal sheets when the magnetic material is manufactured, and it is possible to relatively inexpensively manufacture the magnetic material 3 and the current detector 1. The outer circumferential surfaces of both ends of each metal sheet 3a constituting the magnetic material 3 are tilted, curved surfaces gradually tapered toward a gap 4. Accordingly, unnecessary sections which hardly attribute to the magnetism collection of magnetic flux are not present, thereby achieving further lower costs and saving resources. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
