PURPOSE: A vibration measuring apparatus using a laser and a reflector is provided to fundamentally prevent the malfunction of a sensor sensing vibration using a laser and a reflector for measuring vibration without contact. CONSTITUTION: A vibration measuring apparatus using laser and reflector comprises a light-generating unit(100), a light transmission unit(200), a light sensing unit(300), and a light enlarging unit(400). The light transmission unit is coupled with a vibrator(500). The light transmission unit reflects light transmitted from the light-generating unit. The light sensing unit senses the light reflected through the light transmission unit. The light enlarging unit is installed between the light transmission unit and the light sensing unit. The light enlarging unit enlarges the light through the light transmission unit and transmits the light to the light transmission unit. The light transmission unit comprises a reflector(210) and a coupling unit fixing the reflector on the vibrator.
