A bus bar () comprises: a laminated conductive wire () formed by arranging side by side in the longitudinal direction a first plate-shaped conductive wire () formed by spirally winding stripe conductors () mutually adjacent in the width direction while bringing the opposing inner surfaces closer to each other, and a second plate-shaped conductive wire () formed by spirally winding the stripe conductors () in the direction opposite the direction of the first conductive wire () while bringing the opposing inner surfaces closer to each other, and overlapping these wires () so that the outer surfaces in the width direction face each other; and terminals () joined to the first conductive wire () and the second conductive wire () at both ends of the laminated conductive wire ().

Disclosed is a brushless motor (A) which is an axial gap type brushless motor (A) wherein stators (A,A) comprising a coil () and a rotor () comprising a permanent magnet () are arranged with a gap therebetween in the axial direction. The coil () is a band-like wire which is spirally wound such that the width direction of the band-like wire generally coincides with the direction of the magnetic flux that is generated by the permanent magnet () of the rotor (). Consequently, the axial gap type brushless motor (A) having the above-described structure can be further reduced in eddy current loss in comparison to conventional brushless motors.
