<P>PROBLEM TO BE SOLVED: To provide a current sensor capable of improving measurement accuracy by adjusting the output characteristics of a magnetic sensor while reducing manufacturing cost. <P>SOLUTION: A current sensor of the present invention includes: an annular core 10 consisting of an annular magnetic body divided into a plurality of divided core members 18, 20; a first gap 22 and at least one second gap 24 provided in between the plurality of divided core members 18, 20; and a Hall element 14 provided in the first gap 22. The current sensor has a case 12 formed so as to seal the annular core 10 with a resin, and the case 12 is provided with a second cavity part 28 consisting of a cavity through which a magnetic plate 16 can be inserted into the inside of the second gap 24. <P>COPYRIGHT: (C)2012,JPO&INPIT |
