The present invention relates to a portable pulse notification device and, more specifically, to a portable pulse notification device which enables an aerobic exercise through a pulse notification in real time. The portable pulse notification device according to the present invention includes: a clock type casing unit which is arranged to be wearable on a wrist by including a body case, a first band extended to one end of the body case, and a second band extended to the other end of the body case； a vibration sensing unit which is embedded in at least one band of the first and second bands and senses a pulse, generated in a radial artery, as a vibration by being closely attached to a wrist in case of being worn； a pulse notification control unit which includes a pulse rate data generating end of generating real-time pulse rate data by calculating the sensed pulse in a pulse rate per minute in real time, and a pulse notification control signal generating end of generating a pulse notification control signal in case a real-time pulse rate deviates from the range of a reference pulse rate by determining that the real-time pulse rate is within the range of the preset reference pulse rate； a display unit which displays the real-time pulse rate on a screen by receiving the real-time pulse rate data and displays the state of deviating from the reference pulse rate in case of receiving the pulse notification control signal； and a pulse state notifying unit which shows the pulse notification control signal in at least one of sound or vibration by receiving the pulse notification control signal.본 발명은 휴대용 맥박알림 장치에 관한 것으로, 보다 상세하게는 맥박을 통해 실시간으로 유산소 운동을 가능하게 해주는 휴대용 맥박알림 장치에 관한 것이다.본 발명에 따른 휴대용 맥박알림 장치는, 본체케이스와, 본체케이스의 일단으로 연장되는 제1 밴드와, 본체케이스의 타단으로 연장되는 제2 밴드를 포함하여 손목에 착용 가능하게 마련되는 시계형 케이싱부； 제1 밴드 또는 제2 밴드 중 적어도 어느 하나의 밴드에 내장되며, 착용시 손목에 밀착되어 노동맥에서 발생되는 맥박을 진동으로 감지하는 진동 감지부； 감지되는 맥박을 분당 맥박수로 실시간 산출하여 실시간 맥박수 데이터를 생성하는 맥박수 데이터 생성단과, 실시간 맥박수가 미리 설정된 기준 맥박수 범위인지 여부를 판단하여, 기준 맥박수의
