As a modification of the original embodiment, the shield winding 6 is attached adjacent to either side of the primary conductor winding 1 or the secondary conductor winding 2. The need for the shield winding 6 is as follows.
When the composite member is wound around the core 10 in a spiral shape, the pitch is relatively large, and the adjacent primary conductor windings 1 and 2 are adjacent to each other.
When the spacing between the subsequent conductor windings 2 is relatively wide, there is no fear that the shielding effect will be reduced without adding another shield winding inside the spacing. However, when the pitch is small and the interval between the adjacent primary conductor winding 1 and secondary conductor winding 2 is narrow, another shield winding must be added between them.
The shield effect will be reduced. The additional winding to be added is one of the shield windings 6 indicated by a broken line in FIGS. 1, 3, and 4.

適である。According to the present invention, the primary conductor winding and the secondary conductor winding are alternately wound so as to be magnetically shielded by the conductor winding having a shield function so as to maintain a constant positional relationship. Moreover, the interval between the primary conductor winding and the secondary conductor winding is set to be adjustable to a desired degree or fixed. Further, by attaching the shield winding adjacent to either side of the primary conductor winding or the secondary conductor winding, the shielding effect can be obtained even when the composite member is wound at a relatively narrow pitch. The drop is prevented. Furthermore, since the composite member is wound so as to make the interval between the adjacent primary conductor winding and secondary conductor winding equal,
It is possible for the secondary conductor windings to be alternately and evenly and evenly wound. Therefore, the primary conductor winding and the secondary conductor winding are electromagnetically shielded, and the capacitance therebetween is small, and can be adjusted to a desired degree to be small, and
The electromagnetic coupling between the two is good and the leakage inductance can be reduced. As a result, the common mode noise rejection ratio can be increased, the noise resistance can be improved, and the frequency characteristics can be improved, which is suitable for pulse code communication and data communication using modulation / demodulation.
