A central power supply member for supplying power to windings of a stator of a motor, wherein: a plurality of ring-shaped busbars, each including a power supply terminal (30; 31) and connecting terminals to be connected to the windings on one lateral edge of each busbar, are substantially concentrically accommodated in a holder made of insulating material while being insulated from each other, and power-supply side terminals drawn out from a power supply are to be individually placed on the power supply terminals (30; 31) of the respective busbars and connected to the power supply terminals (30; 31); and wherein the connecting terminals are formed to substantially project radially inward of the busbars in unison, and the power supply terminals (30; 31) are formed to substantially stand up along an axial direction of the busbars; characterized in that terminal blocks are provided with which the power supply terminal (30; 31) and the power-supply side terminal, at least partly placed one over the other, come into contact; the terminal blocks are provided at specified positions of the holder to be able to be temporarily assembled so as not to fall or come off by one or more fitting plates of the holder at least partly fittable into the one or more temporary accommodating grooves of each terminal block; L-shaped or bent auxiliary power supply terminals are provided, each auxiliary power supply terminal comprising an one end and an other end, wherein the other ends of the auxiliary power supply terminals project radially outward of the busbars, the one ends are brought into contact with the outer surfaces of the power supply terminals (30; 31), and the other ends of the auxiliary power supply terminals are to be secured to the power-supply side terminals by bolts on placing surfaces provided on the terminal blocks; each terminal block includes a mounting surface on which the power supply terminal (30; 31) and the one end of the auxiliary power supply terminal at least partly are placed and secured, particularly by a bolt; each terminal block is formed into an L shape or bent shape, including a first portion standing up substantially along a radially outer surface of the holder and a second portion substantially projecting radially outward from a lower position of the first portion; and the mounting surface is formed on an upper position of a radially outer surface of the first portion, the placing surface is formed on an upper surface of the second portion, and an insertion groove, into which the other end of the auxiliary power supply terminal at least partly is inserted, is formed at a position of the first portion substantially aligned with the upper surface of the second portion. a plurality of ring-shaped busbars, each including a power supply terminal (30; 31) and connecting terminals to be connected to the windings on one lateral edge of each busbar, are substantially concentrically accommodated in a holder made of insulating material while being insulated from each other, and power-supply side terminals drawn out from a power supply are to be individually placed on the power supply terminals (30;
