<p><P>PROBLEM TO BE SOLVED: To obtain a current detection device excellent in sensitivity as well as capable of attaining miniaturization. <P>SOLUTION: A first bent part 24 of the bus bar 2 is formed with a plate like conductor 2a and the conductor 2b bent perpendicularly to the 2a. The first magnetic flux 7 made by the conductor 2a of the first bent part 24 and a second magnetic flux 8 made by the conductor 2b are inter link with the sensing surface 19 of the flux detector element 5. The flux detection element 5 is arranged in the bent part 24 in the smaller angle side while contacting to the conductor 2a and 2b or arranged nearby. When the current flows in the bus bar 2, the inside apex of the first bent part 24 is most high flux density, therefore, if the flux detection element 5 is arranged at that point, the magnetic flux caused by the current flowing the bus bar 2 can be measured with a high sensitivity. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
