Summary:[Problem] To provide a method for modifying a catalyst layer whereby the yield in manufacturing a membrane catalyst layer assembly can be improved. [Solution] A catalyst layer correction method for modifying a catalyst layer of a membrane catalyst layer assembly 40, which is manufactured by transferring a catalyst layer 211 formed on a transfer sheet 50 onto an electrolyte membrane 21. In the catalyst layer correction method, a presence or absence of a defect D in the catalyst layer is detected, the defect is removed based on size and position of the detected defect, and a portion P1 from which the defect has been removed is repaired by application thereto of a correcting ink 211B corresponding to the catalyst layer.
