Provided is a stator assembly in which it is possible to reduce the axial thickness and achieve a more compact structure without a bus bar coming into contact with another bus bar, etc. The stator assembly (10) has a stator (11), insulators (12), wires (13), and bus bars (14-17). The stator is provided with a main body part (11a) formed in a ring shape and a plurality of protrusions (11b) formed radially inwards from the main body part. The insulators cover the protrusions. The wires are wound around the protrusions with the insulators interposed therebetween. The bus bars are electroconductive and formed in an annular shape, and are provided so that an electrical connection is established between the wires to which power of an identical phase is supplied. The bus bars are formed so that in cross-section along an axial direction that intersects the radial direction, the axial length is less than the radial length. The insulators are provided with an insertion part cut out inwards from an outer peripheral edge in relation to the radial direction. The bus bars are held through being inserted into the insertion parts. |
