An armature for a rotating electrical machine, including an armature core and a coil wound around the armature core. The segment conductor includes a joint extension portion that extends in the axial direction relative to the armature core from at least one end portion of a conductor edge portion. The coil has an n-layer winding structure and includes an inter-layer joint portion on an axial direction outer side of the armature core. The inter-layer joint portion joining a first and second layer side joint extension portions. At least one of the first and second layer side joint extension portions forming a pair to be joined by the inter-layer joint portion includes an offset bend portion, and the first layer side joint extension portion and the second layer side joint extension portion are joined such that respective joint surfaces thereof oppose each other in a circumferential direction.
