Armature

An armature, comprising:

• a plurality of core constituent members that have teeth extending in a radial direction and are arranged side by side in a circumferential direction;
• a connecting insulator member having an insulator covering the teeth and a guide portion configured to connect two insulators spaced apart in the circumferential direction;
• coils that are wound around the teeth via the insulator;
• and
• a jumper wire that is guided by the guide portion so as to connect two coils, wherein
• the connecting insulator member includes a lower layer insulator member, an intermediate layer insulator member, and an upper layer insulator member that are assembled in the axial direction,
• the guide portion of the lower layer insulator member includes a lower layer arc connecting part having an arc shape when viewed from the axial direction, the guide portion of the intermediate layer insulator member includes an intermediate layer arc connecting part having an arc shape when viewed from the axial direction, and the guide portion of the upper layer insulator member includes an upper layer arc connecting part having an arc shape when viewed from the axial direction, and
• the intermediate layer arc connecting part is arranged above in the axial direction with respect to the lower layer arc connecting part, and the upper layer arc connecting part is arranged outside in the radial direction with respect to the intermediate layer arc connecting part.
