ABSTRACT:
A flat disk type commutator 1 according to the embodiment comprises: a boss 16 which is formed into a thick approximately disk-shape; a plurality of segments 21, each of which is formed into an approximate sector, which are radially arranged on the surface of the boss 16 with an approximately equally space; a riser bar 4 which is electrically connected to each segment 21, as a conductive base material; slits 20 providing a state in which adjacent segments 21 are insulated from each other. A recess 11 is formed at each segment 21. A projecting portion 6 is formed at the riser bar 4. The projecting portion 6 is inserted to the recess 11 in a state in which a copper powder layer 12 and a solder layer 14 is formed at the recess 11, and is soldered. Each riser bar 4 is in a state to electrically connect with the segment 21 by the copper powder layer 12 and the solder layer 14.
