A linear vibrator is provided to improve the reliability of products by preventing a coil from being cut by the downward and upward vibration of a magnet. A linear vibrator includes a case(110), an FPCB(Flexible Printed Circuit Board)(120), first and second coils(131), a spring(140), and a magnet(150). The case(110) has a predetermined space inside. The FPCB(120) is fixed on a lower plane of the case(110). The first and second coils(131) are installed on both sides of the case(110), and are connected to the FPCB(120). A side of the spring(140) is connected to an upper plane of the case(110). The magnet(150) is fixed on the spring(140). A side plane and the other plane of the magnet(150) are arranged to be opposite to the first and second coils(131) respectively. The magnet(150) is upward and downward vibrated by the operation of the first and second coils(131).
