摘要： An electronic device includes a substrate, a first insulating film on the substrate, a second insulating film on the first insulating film, first and second coils respectively in the first and second insulating films, first and second terminals, and first and second connection conductors. The first and second insulating films contact each other so that the first and second coils are magnetically coupled. The first insulating film includes a first non-contact portion not contacting the second insulating film. One of the first and second insulating films includes a second non-contact portion not contacting the first or second insulating film. The first terminal is provided on the first non-contact portion and electrically connected to the first coil. The second terminal is provided on the second non-contact portion and electrically connected to the second coil. The first and second connection conductors are connected to the first and second terminals, respectively.
