The present invention relates to an electrode laminate including: a porous current collector; and a catalyst layer formed on the porous current collector and including a conductive material, wherein the porous current collector has a mesh form. The electrode laminate, a membrane electrode assembly including the same, and a method for manufacturing the same of the present invention can save manufacturing time by directly coating a conductive material on the porous current collector by electroplating without a need to separately cast an electrode to manufacture the membrane electrode assembly. 본 발명은 다공성 집전체; 및 상기 다공성 집전체 상에 형성되고, 전도성 물질을 포함하는 촉매층;을 포함하고, 상기 다공성 집전체가 메쉬 형태인 것인, 전극 적층체를 제공한다. 본 발명의 전극 적층체, 그를 포함하는 막 전극 접합체 및 그의 제조방법은 별도로 전극을 캐스팅하여 막 전극 접합체를 제조할 필요 없이 전기도금에 의해 다공성 집전체에 직접 전도성 물질을 코팅함으로써 제조공정에 걸리는 시간을 절약할 수 있는 효과가 있다.
