1. A rotating electric machine comprising:
an armature that includes
an armature winding, and
an armature core around which the armature winding is wound, wherein:
the armature is provided with a plurality of slots in a circumferential direction thereof;
the armature winding includes a plurality of segmented conductors which are connected;
each of the segmented conductors includes a coil side portion that is housed in the slots and coil end portions that protrude from the armature core at first and second ends in an axial direction of the armature core;
the coil side portions are housed in the slots so as to form 2N+1 layers, where N is a natural number;
the coil end portions are configured to connect two coil side portions that are respectively housed in the slots that are a predetermined pitch apart in the circumferential direction;
the coil end portions are comprised of a first coil end portion type that connects together the coil side portions of differing layers in a radial direction and a second coil end portion type that connects together the coil side portions of a same layer in the radial direction;
the coil end portions of the second coil end portion type are located at both the first and second ends in the axial direction of the armature core;
the armature winding is a lap winding;
at at least one of the first and second ends in the axial direction, the coil end portion includes a joining portion in which conductor end portions of the segmented conductors are connected together; and
the coil end portions of the second coil end portion type connects together the coil side portions in an innermost layer or an outermost layer in the radial direction.
