PROBLEM TO BE SOLVED: To provide a current detector capable of suppressing the effect of noise on an output signal.SOLUTION: A current detector 41 includes a current detection unit 17 comprising a bus bar 13 having a surface mount section 21 and a ferromagnetic core 15 holding the bus bar 13 and provided with an end section 14 having a space in a portion perpendicular to the upper section of the bus bar 13 and facing part of the upper section of the bus bar 13. The current detector 41 further includes a first board 19 on which the current detection unit 17 is surface-mounted, a magnet-sensitive element 23 inserted in a space formed by the end section 14, a second board 25 on which the magnet-sensitive element 23 is mounted and which has an area larger than the magnet-sensitive element 23, and a third board 27 for receiving a signal from the second board 25 and secured in substantially parallel to the first board 19. |
