Abstract
A transformer includes a pair of first coils and at least one second coil. The first and second coils are stacked so that the at least one second coil is interposed between the first coils in a common winding axial direction of the first and second coils. Each of the first coils is covered by insulating films and integrated with the insulating films into an integrated body, so that the first coils are electrically insulated from the at least one second coil.
