PROBLEM TO BE SOLVED: To provide a method of manufacturing a brazing filler metal ring and a method of manufacturing a clad seal ring, by which the clad seal ring can be efficiently manufactured while loss of a brazing filler metal is eliminated; and to provide a method of manufacturing a substrate for electronic component mounting and an electronic device with superior reliability. SOLUTION: The method of manufacturing the brazing filler metal ring 109 includes: a fitting step where a metal material 105 as a brazing filler metal is fitted to a core material 108 so as to be wound around side faces of the core material 108; and a cutting step where the metal material 105 fitted to the core material 108 is cut in a ring shape.
