Abstract

The present invention relates to a method of manufacturing a membrane electrode assembly, the method including the steps of: forming a first catalyst layer on the other surface of a separation membrane having a first carrier film attached to one surface(S1); attaching a second carrier film to the other surface of the separation membrane having the first catalyst layer formed(S2); removing the first carrier film attached to the one surface of the separation membrane(S3); and forming a second catalyst layer on the one surface of the separation membrane from which the first carrier film has been removed(S4), wherein the second carrier film includes a first region corresponding to the first catalyst layer among the other surface of the separation membrane, and a second region that is the remaining region excluding the first region, wherein the second region of the second carrier film has an pressure sensitive adhesive coated on a surface facing the other surface of the separation membrane on which the first catalyst layer is formed.
