Zusammenfassung:	The present invention relates to an electrode for a membrane-electrode assembly and a method for manufacturing the same, wherein the arrangement of a hydrophilic group and a hydrophobic portion of an ionomer is controlled to be bound to a catalyst. The present invention includes the steps of: preparing a dispersion; manufacturing a mixture; manufacturing catalyst slurry; heat-treating the catalyst slurry; treating the heat-treated catalyst slurry with acid; and manufacturing an electrode. The use amount of the ionomer is minimized. 본 발명은 이오노머의 친수성기와 소수성 부분의 배열을 제어하여 촉매와 결합시키는 것을 특징으로 하는 막-전극 접합체용 전극 및 이의 제조방법에 관한 것이다.
