摘要： A transformer includes a bobbin, terminal electrodes, a core, a primary winding, a secondary winding, and an additional winding. The bobbin is made from an electrically insulating material and has a tubular portion defining an internal space. The tubular portion has an outer peripheral surface providing a first through third sections arrayed side by side in an axial direction of the tubular portion. The terminal electrodes are provided at the bobbin for electrical connection to the windings. The core is inserted into the internal space. The primary winding has an insulating layer and is wound over the first section. The secondary winding has an insulating layer and is wound over the third section. The additional winding is wound over the second section and has an insulation layer whose insulating performance is greater than that of the insulation layer of the primary winding and the secondary winding.

摘要： The present invention provides a coil component which is possible to be thinner with less leakage flux toward upward and downward directions, and to sustain a good insulation. The coil component comprises a core including two opposing parts mutually opposing, two side legs mutually connect both ends of the two opposing parts, and a middle leg placed between the two side legs and mutually connect central parts of the two opposing parts, a primary coil, which goes around outer circumference of the middle leg, and a secondary coil, which goes around outer circumference of the primary coil, wherein; a distance between outer perimeter edge of the primary coil and inner perimeter edge of the secondary coil varies along circumferential direction.
