The present invention relates to a head band (1) having a drowsiness prevention function of a driver. The head band comprises: a low frequency generator (10) mounted on an inner surface in both side ends of the head band (1), and having a stimulation member (11) to stimulate meridian and muscle through a low frequency signal to the temple or around the temple of a user a adjusting unit (22) for adjusting strength of a low frequency generator (10) and a switch (21) for adjusting performance and termination of the low frequency generator (10) on the head band (1) a control unit having a PCB (24) formed therein to supply a low frequency electric current to a battery (23) for supplying a power source and a low frequency generator (10) a transceiving means (30) receiving received signal from a remote control unit (35) provided to operate the low frequency generator (10) and control unit (20) in a remote distance for safety of operation and a length adjusting means (40) formed in both side ends of the head band (1) to adjust a length according to a size of the head of driver. Accordingly, driving while drowsy of a vehicle driver is prevented through a low frequency, and a danger of a traffic accident caused driving while drowsy can be preemptively prevented. Through a low frequency electric current to the human body, a low frequency electric current flowing in a human body electric current and stimulation member, nerves and muscles of a driver are stimulated, so he/she can have clean mind and drowsiness can be prevented.COPYRIGHT KIPO 2016본 발명은 운전자의 졸음 기능을 가지는 머리띠(1)에 있어서: 상기 머리띠(1)의 양측 끝단 내부면에 장착되어 운전자의 관자놀이 또는 관자놀이 주변에 저주파신호를 통해 경락 및 근육을 자극하게 자극부재(11)를 구비하는 저주파 발생기(10) 상기 머리띠(1) 상에 저주파 발생기(10)의 실행 및 종료를 조절하는 스위치(21)와 저주파 발생기(10)의 강도를 조절하는 조절부(22)를 구비하고, 전원 공급을 위한 배터리(23)와 저주파 발생기(10) 상에 저주파 전류를 공급하게 PCB(24)를 내장하는 제어부(20) 상기 저주파 발생기(10)와 제어부(20)를 운전 중 안전을 위해 원거리 실행이 가능하도록 구비하는 원격제어부(35)로부터 수신신호를 전달받는 송수신수단(30) 및 상기 머리띠(1)의 양끝단에 운전자의 두상의 크기에 따라 길이 조절이 가능하도록 구비하는 길이조절수단(40
