PROBLEM TO BE SOLVED: To provide a coil unit for use in a current transformer or the like, which allows the reduction in size and cost of the current transformer.SOLUTION: Coil bobbins 30 are structured so as to be connected vertically, by providing combining and connecting parts 31 and 32 for combining and connecting coil bobbins with each other on side surfaces of the coil bobbins 30. Therefore, a plurality of coil bobbins can be attached to a winding machine in a state of being connected to each other to reduce the man-hour for attaching the coil bobbins to the winding machine. In addition, a plurality of coils are constituted of one conductor in coil bobbins connected to each other, so that winding coils of series wiring for use in a winging coil current transformer or the like constituted of a plurality of coils can be constituted not require wiring work between winding coils. |
