A fixing apparatus of a winding device for fixing a drum ferrite core is provided to fix the drum ferrite core by holding the drum ferrite core of a small size through a holder with a built-in electromagnet. A fixing apparatus of a winding device for fixing a drum ferrite core(15) includes a ring ferrite core, a coil(16), and two terminals. The drum ferrite core(15) has upper part and lower part flanges(16,19). The ring ferrite core is attached on an upper surface of the lower part flange(19) of the drum ferrite core(15) by an adhesive to wrap an outer peripheral surface of the upper part flange(16) of the drum ferrite core(15). The coil(16) is wound around the drum ferrite core(15) and the end of the coil(16) is electrically connected to leads of the two terminals respectively. Two terminals are electrically connected to the end of the coil(16) to be attached at regular intervals on a bottom surface of the lower part flange(19) of the drum ferrite core(15) by the adhesive such as an Ag paste.
