Patent abstract
The invention is comprised of a coil group arranging a plurality of terminal-integrated type coils (1), (4) formed by bending a metal sheet in a preset development form and having a predetermined positional relationship, and a magnetic material (7) burying therein the coil group. For example, axes of the plurality of coils (1), (4) constituting the coil group, are arranged in parallel wherein the center point of at least one coil selected from the plurality of coils (1), (4) and the center point of a coil other than the selected coil are in an staggered arrangement. Due to this, an array type choke coil can be realized which is thin overall and operable with a large current in a high frequency band.
