Disclosed is a membrane-electrode assembly obtained by arranging a catalyst layer on both sides of an electrolyte membrane. This membrane-electrode assembly is characterized in that the water flow resistance of the electrolyte membrane obtained by the formula (F1) below is not more than 10 µm g/meq, and the platinum content contained in at least one catalyst layer is 0.02-.020 mg/cm<SUP>2</SUP>. (F1) AA [WATER FLOW RESISTANCE] BB [FILM THICKNESS OF ELECTROLYTE MEMBRANE (µm)] CC [ION EXCHANGE CAPACITY OF ELECTROLYTE MEMBRANE (meq/g)]
