<P>PROBLEM TO BE SOLVED: To provide a current sensor capable of achieving miniaturization and cost reduction while improving detection accuracy. <P>SOLUTION: In a current sensor 1 comprising a core 10 which is annularly formed with a gap 20 and serves as a magnetic path of the magnetic flux generated by the current flowing in a detection object 22 put inside the annular core and a Hall element 12 which is disposed between core end faces 30a and 30b facing each other at a gap 20 and generates an electric signal corresponding to the strength of the magnetic field in the gap 20, each of the core end faces 30a and 30b is formed into a tapered shape in parallel and opposite each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
