Abstract: In an electrolyte membrane for a fuel cell, having nanofiber unwoven cloth buried in an electrolyte resin, the nanofiber unwoven cloth is disposed being exposed only from one face of the electrolyte membrane. The fuel cell includes a MEA having an anode electrode disposed on one face of the electrolyte membrane and having a cathode electrode disposed on the other face thereof, and a pair of separators holding the MEA by sandwiching the MEA therebetween. Thereby, the electrolyte membrane for a fuel cell, the manufacturing method of the electrolyte membrane, and the fuel cell are provided with which the electric power generation property and productivity are improved.
