Abstract: A common mode choke coil includes a quadrilateral core 4; first and second core covers 2, 3 disposed opposite to each other on the upper and lower surfaces of the core 4 so as to cover the outer periphery of the core 4; and rectangular copper wires 8 wound on the opposite side portions of the core 4 of the first and second core covers 2, 3. The second core cover 3 is disposed on a component-mounting face. The first and second core covers 2, 3 include a pair of linear portions surrounding the corresponding opposite sides of the core 4 which linear portions constitute winding portions 5. The lower surface of the second core cover 3 has a pedestal portion 6 which protrudes more toward the component-mounting face than the winding portions 5, and extends out along the component-mounting face in a direction perpendicular to axis lines of the winding portions 5. The lower face at the tip of the protruding part of the pedestal portion 6 has seat faces 6a on which parts of the rectangular copper wires 8 drawn from the winding portions 5 toward the component-mounting face are provided as mounting terminals 12. Tip portions of the rectangular copper wires 8 are bent upward from the seat faces 6a at the edge of the tip of the protruding part of the pedestal portion.

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.
