Short-circuiting member, commutator, and method of manufacturing short-circuiting member

A short-circuiting member which prevents the length in the shaft direction of a commutator from being increased and prevents the kinds of parts of the commutator from being increased. A short-circuiting member comprises a plurality of constituent members each of which has outer and inner circumferences. Each constituent member includes outer circumference terminals disposed along the outer circumference, inner circumference terminals disposed along the inner circumference, and connecting portions for connecting each outer circumference terminal to the corresponding inner circumference terminal shifted by a predetermined angle in a circumferential direction. The outer circumference terminals, the inner circumference terminals, and connecting portions are formed substantially on the same plane. The constituent members are so stacked that the connecting portions of any one constituent member are oriented reversely to those of another constituent member. Any pair of circumference terminals adjacent to each other
