Claims

[Scope of utility model registration request]

A transformer case that houses a low-voltage coil, a high-voltage coil, a high-voltage diode, etc. inside, a resistor case that is attached to the transformer case and houses a focus voltage resistor and a screen voltage resistor, and each of the resistors in the resistor case. In order to fix the resistor and insulate and protect the high voltage part, in a flyback transformer consisting of a resin mold filled with the resistor case, the high voltage part of the resistor case has a double resin mold structure. A flyback characterized in that an insulating resin filling chamber that opens toward the transformer case is formed near the high voltage section, and the insulating resin filling chamber is resin-molded at the same time when the transformer case is filled with the insulating resin.
