PROBLEM TO BE SOLVED: To suppress wrinkling of an electrolytic membrane when bonding a catalyst electrode to the electrolytic membrane.SOLUTION: A manufacturing apparatus 100 of a membrane electrode assembly includes first and second bonding sections 20, 40. In the first bonding section 20, a first catalyst layer 2 is bonded to the entire part of one side of a strip electrolytic membrane 1 by means of first and second hot rollers 23, 24. In the second bonding section 40, a second catalyst layer 3 is bonded to the other side of the electrolytic membrane 1 by means of first and second hot rollers 42, 43. In the second bonding section 40, the electrolytic membrane 1 is fed between the first and second hot rollers 42, 43 from below the gravity direction. |
