摘要：
Rings (4) are each formed between an annular opening (2) and a center hole (3) in an insulating sheet (1). Conductor film (6) is helically deposited on each ring (4) so that the insulating sheet may include a plurality of printed annular coils. Rings (4) are cut from the sheet (1) to provide a plurality of separate, printed annular coils (P).
