<P>PROBLEM TO BE SOLVED: To provide an injection molding nozzle, an injection molding apparatus, and a method of injection molding which can efficiently vibrate melted resin in injection molding, and also to provide an injection-molded product. Ž<P>SOLUTION: The injection molding nozzle includes a channel through which the melted resin 7 filled from a resin filling port 11 flows, an injection port 16 for injecting this melted resin 7 to a mold, an opening and closing pin 4 for opening and closing the injection port by advancing and retreating the pin in an axial direction, a vibrator 2 fixed to this opening and closing pin 4 to oscillate an ultrasonic wave, and an opening and closing pin drive actuator 12 for advancing and retreating the opening and closing pin. The melted resin is vibrated through the opening and closing pin 4 by the ultrasonic wave oscillated from this vibrator 2. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
