Disclosed herein is a linear vibrator, including: a stator including a coil; and a vibrator including a magnet opposite to the coil, wherein the linear vibrator is linearly vibrated due to electromagnetic induction of the coil and the magnet, the magnet is formed in a disc shape in which a cut part is formed by cutting a portion thereof, a magnetic fluid band is formed on an outer peripheral surface of the magnet, and a portion of the magnetic fluid band is in contact with the coil. According to the present invention, there is provided the linear vibrator capable of suppressing weak vibration generated at the time of external impact or movement, previously preventing noise generated as the vibrator applies an impact to the stator due to excessive vibration, and minimizing attenuation of the linear vibration quantity as the cut part that is formed by cutting a portion of the magnet to form the air gap with the coil.
