A generator having an improved radiation characteristic of a diode is provided to improve a temperature characteristic and a generation capacity of the generator by reducing the heat the generated from the diode and discharging the heat. A generator includes an exciter stator, an exciter rotor, a diode(52), a generator rotor(30), a generator stator, and a ring-shaped member(54). The exciter stator receives an external power to generate a fixed magnetic field. The exciter rotor rotates inside the exciter stator, and generates and outputs a first induction current by the fixed magnetic field. The diode rectifies the first induction current. The generator rotor has a coil separation preventing unit for preventing the separation of a generator rotor winding, integrally rotates with the exciter rotor, and is supplied with the rectified first induction current to generate a rotation magnetic field. The generator stator is arranged outside the generator rotor, and generates a second induction current by the rotation magnetic field. The ring-shaped member is fixed around a rotation axis between the generator rotor and the exciter rotor. The diode is installed on the ring-shaped member. The ring-shaped member has a ring-shaped body with coupling holes(56) for screw-coupling with the coil separation preventing unit, and a diode fixing unit(57) installed between the coupling holes to install the diode in the ring-shaped body.
