PROBLEM TO BE SOLVED: To protect deterioration of current detection accuracy caused by a displacement between a magnetoelectric converting device mounted on a circuit board and a magnetic core in a current detector.SOLUTION: In the current detector 1, a container member 41 comprising an insulation case is provided with a board fixing part 46 and core inner edge positioning parts 43a, and a lid member comprising the insulation case is provided with a lid side board pressing part 423. The board fixing part 46 is formed at a position outside an outer edge of the magnetic core 10 and where a first part 501 in the circuit board 50 mounted with a hall element 20 is fixed. Two core inner edge positioning parts 43a contact inner edges of the magnetic core 20 on the side surface and contact a second part 502 and a third part 503 of the circuit board 50 at a top part. The first part 501, the second part 502, and the third part 503 encircle a mount part of the hall element 20 from three directions. The lid side board pressing part 423 grips the circuit board 50 between the core inner edge positioning parts 43a and itself. |
