A fuel pump may have an armature 16 and a pump section 10. The armature 16 may include a shaft 17, a core 21 fixed to the shaft 17, and coils 29 that is wound around the core 21 . The pump section 10 is rotatably driven by the shaft 17. Preferably, the armature 16 includes a guide 34 that guides the coils 29 on the outside of the outer surface of the shaft 17 on at least at one axial end of the core 21. The coils 29 are wound around opposing slots. On the end where the guide 34 is provided, the coils 29 are preferably guided by the guide 34, and thereby are wound to detour around the region in proximity to the shaft 17.
