Patent ID: 7212095

Claim:
An inductive element having a first direction, a second direction, and a stacking direction, said inductive element comprising: a plurality of alternating individual sheets of conducting and insulating layers forming a stack wherein each conducting layer is integrally formed from a solid sheet into a U-shaped conductive layer such that every U-shaped conductive layer is located in a substantially same position along the first direction and the second direction and is located a distance from an adjacent U-shaped conductive layer along the stacking direction; an embedding material filled in an area between legs of the U-shaped conducting layers; and a bridge conductor which bridges an opening edge of the U-shaped conducting layer to an opening edge of the next U-shaped conducting layer to form a coil, wherein said U-shaped conducting layers are connected by said bridge conductor by skipping one of said U-shaped conducting layers so as to form two sets of rectangular helical coils.
