Abstract: A winding component includes a core that surrounds an outer circumference of a coil and end surfaces of flanges to form a closed magnetic circuit, in which notches through which end portions of the coil are drawn outward are so formed in the flanges that each of the notches extends radially inward from an outer circumferential edge of the corresponding flange, a wall that surrounds each of the notches such that the wall stands axially outward on the flange, a thick portion in a winding part in correspondence with the notches and thicker than other portions of the winding part, and a lid formed of a sidewall between an outer circumferential surface of the wall and the core and covers the outer circumferential surface of the wall and a top plate at an axially outer end of the sidewall and covers an opening in the wall.

Abstract: A transformer in which the high-voltage and low-voltage coils are easily laminated when they are alternately laminated in their axial directions, improving power efficiency. The transformer includes: a high-voltage coil including a wire wound around a cylindrical winding drum of a bobbin which is provided with flanges on both ends of the winding drum; a low-voltage coil formed of a flat plate member having an open ring shape, the low-voltage and high-voltage coils being alternately laminated in their axial directions; and a cover member which has a ring plate shape and is coaxially laminated on an outside of a laminate in an axial direction. The low-voltage coil is between the high-voltage coil and the cover member, and a wall portion protruding in the axial direction from the bobbin of the high-voltage coil and a wall portion protruding in the axial direction of the cover member are alternately disposed.
