ABSTRACT:
A transformer is provided with a coil portion containing primary windings and a secondary winding. Cores sandwich the coil portion. Each of these windings includes a toroidal-shaped portion that is formed by winding flat type wires in a toroidal shape and by overlapping these flat type wires. Edge portions of this flat type wire are derived from the toroidal-shaped portion respectively. A plurality of windings and the cores are arranged along an overlapping direction of the flat type wires. employed, By this structure, a copper loss caused by the skin effect can be reduced and the electromagnetic coupling conditions between the windings can be improved.
