The present invention relates to an automatically controllable electrode manufacturing device including: a dispersion supply unit that supplies a conductive material dispersion in which a conductive material is dispersed in a solvent; and a slurry production unit that is connected to the dispersion supply unit through a first transport path to receive the conductive material dispersion, and produces an electrode slurry by mixing an electrode active material, a binder, and the conductive material dispersion, wherein the first transport path includes a sensing unit that measures at least one of physical properties such as a flow rate, pressure, viscosity, particle size, and degree of dispersion of the conductive material dispersion and a first valve that controls flow and the flow rate of the conductive material dispersion, and wherein the automatically controllable electrode manufacturing device further includes a control unit that controls the first valve by comparing the physical properties sensed by the sensing unit with a preset physical property value. The automatically controllable electrode manufacturing device can manufacture electrodes with excellent performance and uniform quality. 본 발명은 자동제어형 전극 제조장치에 관한 것으로, 도전재가 용매상에 분산된 도전재 분산액을 공급하는 분산액 공급부 및 상기 분산액 공급부와 제1 이송로로 연결되어 도전재 분산액을 공급받고, 전극 활물질, 바인더 및 도전재 분산액를 혼합하여 전극 슬러리를 제조하는 슬러리 제조부를 포함하는 자동제어형 전극 제조장치이되, 제1 이송로에는 도전재 분산액의 유량, 압력, 점도, 입도 및 분산도 중 적어도 하나 이상의 물성을 측정할 수 있는 센싱부, 및 도전재 분산액의 흐름과 유량을 제어하는 제1 밸브를 포함하며, 자동제어형 전극 제조장치는 센싱부에 감지된 물성을 기설정된 물성값과 비교하여 제1 밸브를 제어하는 제어부를 더 포함한다.
