    摘要： The present invention provides a catalyst-coated membrane and a membrane-electrode assembly that can easily and surely achieve a polymer electrolyte fuel cell having excellent durability, in which the decomposition/degradation of a polymer electrolyte membrane can be suppressed, and a decrease in initial characteristics can be prevented sufficiently for a long period of time even when the polymer electrolyte fuel cell is frequently started and stopped. In the catalyst-coated membrane that includes an anode catalyst layer, a cathode catalyst layer, and a hydrogen ion conductive polymer electrolyte membrane interposed between the anode catalyst layer and the cathode catalyst layer, a peripheral area of at least one of the anode catalyst layer and the cathode catalyst layer is provided with a decrease portion in which the mass of the electrode catalyst per unit area of the catalyst layer decreases from the inner side toward the outer side.
