PROBLEM TO BE SOLVED: To provide an electrolyte membrane with a reinforcing material which reduces cost and is unlikely to change a dimension, an electrolyte membrane with a support, and a catalyst layer-electrolyte membrane laminate with support.SOLUTION: An electrolyte membrane 2 includes a reinforcing material 3 and the reinforcing material 3 protrudes outside from at least four corners of a rectangular outer edge 20 of the electrolyte membrane 2 and/or a part of at least opposing two side edges of the outer edge 20 of the electrolyte membrane 2. An electrolyte membrane 10 with a support includes, the electrolyte membrane 2 and a frame-shaped first support 4 disposed so as to cover at least a portion 30 of the reinforcing material 3 protruding from the electrolyte membrane 2 from at least one surface. A catalyst layer-electrolyte membrane laminate 100 with a support includes the electrolyte membrane 10 with the support and catalyst layers 5 disposed on both surfaces of the electrolyte membrane 2. |
