Abstract

An inductor device includes a resin film, a first base conductor layer formed on one surface of the resin film and having a first pad, a second base conductor layer formed on the other surface of the resin film and having a second pad, a through-hole penetrating from the first pad to the second pad, a through conductor filled in the through-hole and provided to connect the first pad and the second pad each other, a first insulating layer formed on the one surface of the resin film and having an opening arranged on the first base conductor layer, and a first conductor part formed on the first base conductor layer in the opening of the first insulating layer. A first conductor pattern layer includes the first base conductor layer and the first conductor part. The first conductor pattern layer has a convex sectional shape.

Dependent claims

An inductor device comprising:

a resin film;
a first base conductor layer formed on one surface of the resin film and having a first pad;
a second base conductor layer formed on the other surface of the resin film and having a second pad at a position corresponding to the first pad;
a through-hole penetrating from the first pad to the second pad via the resin film in a sectional height direction of the inductor device;
a through conductor filled in the through-hole and provided to connect the first pad and the second pad each other;
a first insulating layer formed on the one surface of the resin film and having an opening arranged on the first base conductor layer;
and
a first conductor part formed on the first base conductor layer in the opening of the first insulating layer,
wherein a first conductor pattern layer includes the first base conductor layer and the first conductor part, and a width of the first base conductor layer is greater than a width of the first conductor part, the width of the first base conductor layer and the width of the first conductor part being measured in a sectional width direction of the inductor device, the sectional width direction of the inductor device being perpendicular to the sectional height direction of the inductor device.
