Provided is a method for modifying a catalyst layer whereby a yield in manufacturing a catalyst coated membrane can be improved. According to the method for modifying a catalyst layer, the catalyst layer of a catalyst coated membrane (40), which is manufactured by transferring the catalyst layer (211) formed on a transfer sheet (50) on an electrolyte membrane (21), is modified. The method for modifying a catalyst layer comprises detecting the presence or absence of a defect (D) in the catalyst layer, removing the detected defect on the basis of the size and position of the defect, and then applying a correcting ink (211B) corresponding to the catalyst layer to a part P1, from which the defect has been removed, to thereby correct the catalyst layer. 提供种催化剂层修正方法，能够提高制造时的膜催化剂层接合体的成品率。催化剂层修正方法用于对通过将形成在转印片(50)上的催化剂层(211)转印到电解质膜(21)上来制造的膜催化剂层接合体(40)的催化剂层进行修正。催化剂层修正方法中，检测催化剂层内有无缺陷(D)，根据所检测出的缺陷的尺寸和位置去除缺陷，对去除了缺陷的部分(P1)处涂布与催化剂层对应的修正墨(211B)来进行修补。
