PROBLEM TO BE SOLVED: To provide a method for manufacturing a commutator in which short-circuit member and a segment can be bonded easily and reliably. SOLUTION: Segments 1-24 provided at each radial outside end of first and second short-circuit pieces 115 and 116 constituting a short-circuit member 112 and on the outer periphery of a commutator main body 111 are provided, respectively, with adjacent connection protrusions 115b, 116b and 31 such that mutual distal end faces 115c, 116c and 31a continue on the same plane. The distal end faces 31a, 115c and 116c of the connection protrusions 31, 115b and 116b are subjected to Tig welding or laser welding and the distal ends of the connection protrusions 31, 115b and 116b are bonded mutually.
