Claim 0:
1. An electronic device, comprising:
a first substrate;
a first insulating film provided on the first substrate;
a first coil provided in the first insulating film;
a second insulating film provided on the first insulating film;
a second coil provided in the second insulating film, the first insulating film and the second insulating film contacting each other so that the first coil and the second coil are magnetically coupled, the second insulating film having a front surface contacting the first insulating film, the second insulating film contacting a front surface of the first insulating film, the first insulating film including a first non-contact portion not contacting the second insulating film, the first insulating film including a second non-contact portion not contacting the second insulating film, the second non-contact portion being separated from the first non-contact portion;
a first terminal provided on the front surface of the first insulating film at the first non-contact portion, the first terminal being electrically connected to the first coil;
a second terminal provided on the front surface of the first insulating film at the second non-contact portion, the second terminal being electrically connected to the second coil;
a first connection conductor connected to the first terminal, the first connection conductor being electrically connected to the first coil via the first terminal;
a second connection conductor connected to the second terminal, the second connection conductor being electrically connected to the second coil via the second terminal;
a resin member sealing the first substrate, the first insulating film, the second insulating film, the first connection conductor, and the second connection conductor;
a first external terminal provided on a first surface region of the resin member and electrically connected to the first connection conductor; and
a second external terminal provided on a second surface region of the resin member and electrically connected to the second connection conductor, the second external terminal being apart from the first external terminal.
