PROBLEM TO BE SOLVED: To provide a coil feeder structure of a synchronous motor which can realize with space-saving advantage a good workability in connecting coil wires, and a prevention of dispersion of coil resistances for respective phases, and a distribution/concentration of coil wires by the simple connection of coil wires. SOLUTION: Bus bars 70, 71, 72 for use in phases and a bus bar 73 for use in neutral point are overlapped one another in axial direction via clearances, thus forming a laminated bus bar. The laminated bus bar is arranged along the end of a stator 4, and coil connections 70c, 71c, 72c of the bus bars 70, 71, 72 for use in phases and a coil connection portion 73b of the bus bar 73 for use in neutral point are paired for each phase in the condition of the laminated bus bar, and the plurality of pairs of the coil connections are arranged in the proximity to the positions of coils 42U, 42V, 42W of respective phases which are in correspondence relation to the coil connections of respective pairs.
