Claims

[Claims for Utility Model Registration] 1. A ferromagnetic core in which a magnetic gap is provided in at least a part of a magnetic path having a circular shape, a magnetic sensing element placed in the magnetic gap, and at least the magnetic sensing element. In the current detector, the magnetic sensing element is mounted on the circuit mounting board, and the magnetic gap end face of the ferromagnetic core and the circuit mounting board are connected to each other. The circuit mounting board and the ferromagnetic core are combined and insulated so that the plate surfaces are substantially parallel to each other and the part of the circuit mounting board where the magnetic sensing element is mounted is located within the magnetic gap. 1. A current detector, characterized in that the current detector is housed in a flexible case, and the circuit terminals of the circuit mounting board are held in the case. 2 Utility Model Registration Scope of Claims In the current detector set forth in claim 1, the case is such that the adjustment component mounted on the circuit mounting board is exposed while the circuit mounting board is housed in the case. What is claimed is: 1. A current detector characterized in that a cover case is provided in a portion of the case that covers the circuit mounting board so as to cover an exposed portion of the adjustment component. 3. In the current detector described in Claim 2 of the Utility Model Registration, the case is made of a ferromagnetic material or a highly conductive material so as to overlap at least a portion of the housed circuit mounting board. A current detector characterized in that a shielding plate is housed therein.
