Abstract
A connection member for supplying a stator winding with a current is constituted by covering a bus bar with a insulating resin. The bus bar is formed in an arc-like shape in the thickness direction of a belt-shaped conductor. Additionally, a weld zone formed on the bus bar has a projection portion projecting in the width direction, a first bent portion bent outside the arc from the projection portion in the thickness direction, and a second bent portion with the tip end thereof folded back in the width direction to allow the tip end of the second bent portion to be welded to a terminal on the stator winding.
