<p><P>PROBLEM TO BE SOLVED: To provide an interboard transmission system which suppresses the interference between the coil for power and the coil for communication, facilitates handling of the coils of the interboard transmission system, reduces the cost of coils and improves processability, and to provide an electronic device and an apparatus. <P>SOLUTION: A composite coil 1 includes: a first coil pattern 3 provided in the upper surface of a first circuit board 2; a second coil pattern 5 provided in the underside of a second circuit board 4; a connection terminal 7 for connecting the first circuit board 2 and the second circuit board 4; and a third coil pattern 6 provided in the upper surface of the second circuit board 4. Further, since the first circuit board 2 and the second circuit board 4 are connected by the connection terminal 7, a third coil pattern 6 constitutes a second coil 17 while a first coil 16 is constituted by the first coil pattern 3, second coil pattern 5, and connection terminal 7. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
