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: There is provided a winding component capable of reducing the core temperature compared to the past even in a usage scenario where the amount of core heat generation is great, and whose size and weight may be reduced as a result. The present invention is a winding component including a coil (2) and a pair of upper and lower cores (4, 5) that form a closed magnetic path by surrounding an outer perimeter of the coil (2), the winding component having a bottom surface of the lower core (5) mounted on a housing (1) with a heat dissipation function, where a metal plate (7) having a higher thermal conductivity than the lower core (5) is attached to an outer side surface (6) of the lower core (5).
