Abstract: A release liner used for manufacturing a membrane electrode assembly includes one or more first films formed of a material having a releasing property, and a second film bonded to the first films and having a tensile strength higher than a tensile strength of the first film. The first films are formed of polytetrafluoroethylene (PTFE) having a non-bonding property and the releasing property.
