<p>PROBLEM TO BE SOLVED: To provide an inverter transformer attachable even to the thin and long space of a narrow width. SOLUTION: The outer shape of the cross section of the winding shaft 12 of a bobbin 10 is turned to an almost elliptic shape, the side of the narrow width is turned to a side face to which the terminals 21 and 22 of the base part 11 of the bobbin 10 are attached, and the winding shaft 12 is integrally molded at the base part 11. Also, a center leg 62 whose cross section is elliptic is formed at the center part of one core 60, and outer legs 63 are formed at four corners, respectively. The center leg 62 is inserted to the hole of the winding shaft 12, and the outer legs 63 are abutted to the core 50.</p> |
