Abstract: A transformer capable of readily ensuring a predetermined insulation distance with no increase in the overall size of the transformer and further capable of reducing the number of constituent parts to achieve cost reduction. According to the present invention, the transformer includes a first bobbin having a wire winding section and a flange formed at an end of the wire winding section, a first coil wound around the wire winding section of the first bobbin, a second coil disposed coaxially with the first coil and adjacent to the flange, and a core disposed around the outer circumferences of the first and second coils to form a closed magnetic circuit, and a tubular protrusion that axially extends and surrounds the outer circumference of the second coil is formed along an outer circumferential portion of the flange of the first bobbin.

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.
