PURPOSE: A load cell of an electronic parking brake device is provided to facilitate a process of assembling a spring into a sensor case to output stabilized sensing values and secure stable operability of the electronic parking brake device. CONSTITUTION: A load cell of an electronic parking brake device includes a sensor case(1), a magnet(5), a sensor shaft(7), a first spring(9), a second spring(11), and a hall sensor(13). The magnet is included in a slider slidably set inside the sensor case. The sensor shaft is extended from the slider to the outside of the sensor case. The first spring is installed in the extended part of the sensor shaft. The second spring is installed opposite to the first spring of the slider. The hall sensor senses the movement of the magnet.
