Abstract: A membrane electrode assembly for a polymer electrolyte fuel cell including catalyst layers with improved flexibility. A membrane electrode assembly according to the present embodiment in which a polymer electrolyte membrane is sandwiched between an anode-side catalyst layer and a cathode-side catalyst layer each of which includes carbon particles supporting catalyst particles, a polymer electrolyte, and fibrous substances. A difference between maximum lengths of cracks formed in the catalyst layers of the membrane electrode assembly before and after a bending test is 1200 μm or less.
