An electroosmotic pump according to one embodiment of the present invention comprises: a membrane allowing the movement of a fluid; and first and second electrodes respectively provided on both sides of the membrane, wherein the first and second electrodes are electrodes made of a non-porous substrate material and an electrode material coated thereon, and have at least one fluid passage formed therein, and wherein the fluid moves through the fluid passage by means of an electrochemical reaction between the first and second electrodes. Une pompe électro-osmotique selon un mode de réalisation de la présente invention comprend : une membrane permettant le mouvement d'un fluide ; et des première et seconde électrodes disposées respectivement sur les deux côtés de la membrane, les première et seconde électrodes étant des électrodes constituées d'un matériau de substrat non poreux et d'un matériau d'électrode appliqué dessus, et au moins un passage pour le fluide formé à l'intérieur, et le fluide se déplaçant à travers ledit passage au moyen d'une réaction électrochimique entre les première et seconde électrodes. 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, 제1 전극 및 제2 전극의 전기화학 반응에 의해, 유체 이동 통로를 통해 유체가 이동한다.
