A tansy 3a is soldered to the relay board 1a.
However, such a fixed-side transformer has the relay board 1a on the side facing the rotating-side transformer 8, and therefore has the disadvantage that the number of channels cannot be increased due to the limitation of φD 1 of the rotating-side transformer 8. Therefore, the methods shown in FIGS. 5 to 7 can be considered as a method for solving this drawback. That is, the flexible substrate 4 is bonded to the back surface of the core 2c, so that a large number of channels can be obtained.
