The copper wires 5 of a are connected in the order of arrangement. Therefore, the copper foil pattern 3a at the right end in FIG. 3 of the flexible substrate 31 is not connected. Further, the outer ends of the first coil body 1 and the second coil body 2 are also connected by a flexible substrate 32 as shown in FIG. The flexible substrate 32 is also the first. One more copper foil pattern 3b than the number of bronze statues 5 of the second coil bodies 1 and 2 is formed, but this copper foil pattern 3b allows the terminal 1b of the first coil body 1 to be
The copper wire 5 of the terminal 2b of the second coil body 2 is connected to the copper wire 5 of the terminal 2b of the second coil body 2 with the arrangement order shifted by one. That is, the copper foil pattern 3b at the left end of the flexible substrate 32 in FIG.
has one end as the input end IN, which is not connected to the statue 5 of the terminal 2b of the second coil body 2, and the other end as the first coil end 1.
It is connected to the copper wire 5 at the left end of the terminal 1b in the figure. In addition, the copper foil pattern 3 at the right end of the flexible board 32 in FIG.
One end of b is connected to the copper wire 5 at the right end in the figure of the terminal 2b of the second coil body 2, and the other end is not connected to the copper wire 5 at the terminal 1b of the first coil body 1 as an output @OUT.

Therefore, the current input from the input terminal IN of the copper foil pattern 3b at the left end in FIG. 4 of the flexible substrate 32 flows from A in FIG. 3. Through the flexible substrate. The second coil body 2 passes through the copper foil pattern 3a at the left end in FIG.
Enter the bronze statue 5 on the left side of the diagram, then enter the image 9 in the diagram E
2 from the left end of the flexible substrate 32 at point F shown in the figure.
After that, the current flows from the left end of the first coil body 1 to the second statue 5 via the second copper foil pattern 3b, and then from the left end of the first coil body 1 to the right end by the flexible board 3□. It shifts and is finally output from the output end OUT of the copper foil pattern 3b at the right end of the flexible substrate 32.

Next, the case of making the above-mentioned aligned winding coil will be explained.

First, the inner end of a flat cable 4 for making the first coil body 1 and the inner end of another flat cable 4 for making the second coil body are connected to a flexible substrate 3 as shown in FIG. Connect with. Thereafter, the flat cable 4 is wound to form the first coil body 1. Next, another flat cable 4 is wound in a direction opposite to the winding direction of the first coil body 1 to form a second coil body 2. At this time, the first coil body 1
and the second coil body 2 are provided coaxially and adjacently in the winding axis direction.

Then, the outer ends of the first coil body 1 and the second coil body 2 are connected by a flexible substrate 32 as shown in FIG. 4, thereby creating an aligned winding coil.

These flexible substrates 31+32 and the first. The connection of the second coil body 1.2 will be explained with reference to FIG. FIG. 5 shows an example of the connection between the flexible board 3I and the first coil body 1. After alignment, when the two are bonded under heat and pressure, the hardened insulating and adhesive covering material 6 is softened, and the copper wire 5 and the copper foil pattern 3a are electrically connected. When pressurized and cooled in this state, the adhesive covering material 6 hardens, and the first coil body 1 and flexible substrate 3. The connection is maintained both mechanically and electrically.

Further, after removing the coating material 6 with chemicals and exposing the copper wire, the copper wire 5 and the flexible substrate 3. ．． Electrical connection and mechanical fixation can also be achieved by applying adhesive between the 32 copper foil patterns and pressurizing and fixing them.

In the above embodiments, the inner terminals of the first coil body 1 and the second coil body 2 are treated as follows. This was done before winding the second coil body 1.3, but the first. If the winding diameter of the second coil body 1.2 is a dog and a large internal space can be obtained, then the first coil body 1.2 can have a large internal space. Second
Coil body 1.2 inner terminal treatment is done in the first step. This may also be done after winding the second coil body 1.2.
