On the other hand, if the bottom support plate 3 is made of metal or synthetic resin and the through pipe 5 is made of paper or synthetic resin, a small hollow cylindrical part 4a is further formed on the upper center surface of the recessed part 4 as shown in FIG. The base of the penetrating pipe 5 can be inserted into the small cylindrical part 4a and fixed by an adhesive 4b.

In this case, it is possible to manufacture the toroidal coil 1 and the mounting bolt 8 without positioning them with high precision, and since the bottom support plate 3 substantially only extends to the bottom of the toroidal coil 1, the bottom support plate 3 is formed of metal. However, the amount of metal materials used can be greatly reduced, and the external size can be made smaller.
Since it is made of metal material, it also has good heat dissipation.
