PROBLEM TO BE SOLVED: To provide an integrated bobbin for a fly-back transformer which can be formed at a low price in a simple structure by forming a shared pin and can be used for a low-voltage bobbin and a high-voltage bobbin. SOLUTION: This integrated type bobbin for a fly-back transformer is constituted of a cylindrical hollow bobbin part 21, which is wound on the outer circumferential surface of a low-voltage coil 22, a plurality of low-voltage pins 38 which are fitted to the lower side of the bobbin part 21, an insulating film 26, a high-voltage coil 24, a plurality of high-voltage pins 37 which are fitted to one side of the upper and the lower ends of the outer circumferential surface of the high-voltage coil 24, a shared pin 36 for lead out of an automatic luminance control voltage, the one end of which is connected to one of a plurality of low-voltage pins 38 and other end is connected to one of a plurality of high-voltage pins 37. |
