Abstract
A stator includes: a stator core having a plurality of slots and teeth parts; and coils each formed by winding a flat conductor and disposed in the slots. Of the corners of the rectangular cross-section of the flat conductor, a first corner located on the inner circumference side of the coil when the flat conductor is wound to form the coil is provided with a round chamfer having a radius larger than that of another corner. When the coil is inserted into the slots of stator core elements, the rectangular cross-section of the coil is disposed such that the first corner faces toward the outer circumference side of the stator.
