A method for manufacturing a distributed straight-angle armature winding according to the present invention comprises a step (a) of preparing a raw material in which at least a pair of intra-slot winding areas and an end winding area provided between the pair of intra-slot winding areas are continued, a step (b) of forming an inclined surface by processing a contact surface in contact with an inner surface of a slot of at least a stator of the circumferences of the pair of intra-slot winding areas, and a step (c) of bending a space between the end winding area and the intra-slot winding area.
