The present invention relates to an electroosmotic pump, a manufacturing method of an electrode, a fluid pumping system using the same, and an operating method of the system. The electroosmotic pump according to one embodiment of the present invention comprises: a membrane which allows movement of a fluid; and a first electrode and a second electrode respectively provided on both sides of the membrane. An electrode composed of a non-porous substrate material and an electrode material coated thereon, and at least one fluid movement passage is formed in the first electrode and the second electrode. The non-porous substrate material is a plate-shaped substrate containing at least one of a conductive material, a semiconductor material, and a non-conductive material. Presented is the electroosmotic pump replaced with various electrode materials. 본 발명의 일 실시예에 따른 전기삼투펌프는 유체의 이동을 허용하는 멤브레인; 및 멤브레인의 양측에 각각 마련된 제1 전극 및 제2 전극을 포함하되, 제1 전극 및 제2 전극은 비투과성 기저물질(non-porous substrate material)과 그 위에 코팅된 전극 물질로 이루어진 전극으로서, 적어도 하나 이상의 유체 이동 통로가 형성된 것이고, 상기 비투과성 기저물질은 전도성 물질, 반도체 물질 및 비전도성 물질 중 적어도 하나를 포함하는 판상형 기재인 것을 특징으로 한다.
