    • PROBLEM TO BE SOLVED: To provide a method of manufacturing a combustor structural member which is formed of a plate-like assembly with hollow flow passages comprising two plate-like members brazed to each other without causing cracking while maintaining the positional accuracy of the hollow flow passages. SOLUTION: This method of manufacturing a combustor structural member, the method comprising a plate-like assembly formation step of brazing a first plate-like member 4a formed from a heat-resistant alloy, and a second plate-like member 4b formed of a heat-resistant alloy and having a plurality of fins 5 on the surface with the fins 5 facing the first plate-like member 4a by interposing a brazing filler metal including a melting-point lowering element between the two plate-like members, thereby forming a plate-like assembly, a press formation step of press-forming the plate-like assembly to form a combustor structural member of a desired shape, a strain location identification step of identifying strain locations where the strain generated during the press formation step exceeds a predetermined value in accordance with the shape of the combustor structural member, a localized heating step of locally heating locations in the plate-like assembly corresponding to the strain locations identified in the strain location identification step, and a cold press formation step of press-forming the plate-like assembly at temperatures of the heated locations corresponding to the strain locations maintained at a desired temperature.
