1. A stator comprising:
a stator core; and
a stator winding installed in the stator core,
the stator winding being configured by including multiple conducting wires constituted by conductors respectively coated with insulating films,
each of the conducting wires comprising:
an exposed portion at a leading end, where the conductor is exposed; and
a covered portion in which the conductor remains coated with an insulating film,
wherein a pair of exposed portions of different conducting wires are joined together at a coil end section of the stator winding,
wherein the covered portion of each conducting wire of the different conducting wires has a depression as a plastic deformation at an edge thereof corresponding to the leading end of the conducting wire,
wherein the depression of the covered portion is formed by crushing the conductor and the insulating film all together on the covered portion, and has a given depth measured from the insulating film of the covered portion to a part of the conductor directly under the insulating film,
wherein an edge of the insulating film enters a depressed part of the conductor at which the depression of the covered portion is formed,
wherein the exposed portion has a depression,
wherein the depression of the covered portion and the depression of the exposed portion are formed across a boundary of the depression of the covered portion and the depression of the exposed portion, and
wherein a depth of the depression of the covered portion at the boundary is deeper than an adjacent part that is not depressed to the boundary of the exposed portion.
