ABSTRACT:
In a first secondary-side bobbin50A, a roll surface of a winding section SA2is located outward in radial direction with respect to a roll surface of a winding section SA1in the vicinity of a groove55A, while a roll surface of a winding section SA3is located outward in radial direction with respect to the roll surface of the winding section SA2in the vicinity of a groove56A. Furthermore, the two winding sections SA2, SA3cross each other so that the respective roll surfaces have substantially oval-coin-shaped cross sections and the respective major axis lines on the cross sections of the respective roll surfaces cross each other when viewed from the Y-axis direction.
