ABSTRACT:
An adhering process of adhering a winding, after the winding is wound on the bobbin, to a bobbin entirely or partly with an adhesive tape, for the purpose of reliably fixing the winding to the bobbin, increases the manufacturing cost of a transformer. To solve this problem, a primary winding (13) is wound on a winding core (111). Extracting portions of the primary winding (13) are caused to intersect, and their terminal ends are connected to terminals (14) which oppose each other through the winding core (111) and which are arranged within a region having end portions of a winding space of the winding core (111) as boundaries.
