Abstract
The carbon commutator of the present invention comprises a plurality of segments having ends which are sliding members on a brush and the other ends to which conductive terminal members are attached, wherein the segments are arranged in a circumferential direction on an insulating boss member and are insulated from each other, carbon layers being formed on the sliding member sides of the segments, metal layers being formed between the carbon layers and the conductive terminal members by sintering a first material of a principal component of the conductive terminal member with a second material which can alloy with the first material.
