Abstract:
A thin-film coil comprising:a coil-shaped first patterned conductor layer; a first insulating layer that fills a space between turns of the first patterned conductor layer and that is flattened together with one of surfaces of the first patterned conductor layer so that the first insulating layer and both upper and lower surfaces of the first patterned conductor layer are coplanar; a second insulating layer located on the first patterned conductor layer and the first insulating layer; a coil-shaped second patterned conductor layer located on the second insulating layer; a first connecting portion connecting one of ends of the first patterned conductor layer to one of ends of the second patterned conductor layer; and a second connecting portion connecting the other of the ends of the first patterned conductor layer to the other of the ends of the second patterned conductor layer.
