<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive current detecting apparatus capable of detecting a current with a high accuracy by inhibiting an effect of a neighboring bus bar on a magnetic field when a plurality of bus bars are parallelly arranged on the basis of a simple configuration requiring only appropriate setting of a shape and arrangement of each part of the bus bars. <P>SOLUTION: The current detecting apparatus, assuming at least one of the plurality of parallelly arranged bus bars 2 to be a target bus bar 3, detects the current I on the basis of the magnetic field B near the target bus bar 3. A sensor section 6 detecting the magnetic field B in a predetermined magnetic field detecting direction S is disposed near a detection part of the target bus bar 3, so that the magnetic field detecting direction S is nearly perpendicular to an extending direction L of the target bus bar 3 at the detection part. The extending direction L of each part of the neighboring bus bar 4 to the sensor section 6 is set so that nothing may pass through the sensor section 6 in a direction parallel to the magnetic field detecting direction S within an extending orthogonal plane 5 perpendicular to the extending direction L of each part of the neighboring bus bar 4 disposed adjacent to the target bus bar 3. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
