PURPOSE: A structure of a bobbin is provided to prevent the short of a coil by improving the structure of the bobbin. CONSTITUTION: A supporting plate(20) is formed lower than both sidewalls(12,12') of a coil winding groove(10) to generate a step. In withdrawing a coil, the contact with a guiding groove(40') is prevented. Thereby, the short of the coil by contacting to the guiding groove is minimized. Moreover, the efficiency of a process is improved and the defective ratio is reduced certainly.
