In addition, installing cored 160 in perforation hole portion 141, thus lattice 140 is relative to the 1st communication coil 120a
Carry out the positioning of the 2nd communication coil 130a.The 1st communication is with the center of coil 120a and the 2nd communication coil as a result,
The leakage of magnetic flux caused by the Centre position deviation of 130a is reduced.Specifically, the central axis with iron core direction,
In i.e. so-called horizontal direction, the leakage of magnetic flux caused by Centre position deviation is reduced.
In addition, the 1st communication coil 120a and the 2nd communication coil 130a has the iron core 160 being integrally formed, therefore
The leakage of magnetic flux caused by gap between the iron core of 2 communication coils is reduced.
