A method of manufacturing an electrochemical device capable of improving output efficiency and obtaining an electrochemical device having excellent durability such as thermal durability, chemical durability, and strength durability. To provide. A method for manufacturing an electrochemical device including a first pole, a second pole, and an ion exchange membrane 2 sandwiched between these electrodes, After forming a catalyst layer 1a containing a catalyst substance such as platinum and polyvinylidene fluoride, an ion exchange group such as a sulfonic acid group is bonded to the polyvinylidene fluoride of the catalyst layer 1a, and the resulting ion exchange group-containing Using a catalyst layer 1b for at least one of the first pole and the second pole; Manufacturing method of electrochemical device.
