A fuel pump includes a stator core that has teeth being circumferentially arranged. Coils are formed by concentrically winding a wire around each of the teeth. The coils circumferentially generate magnetic poles in inner circumferential peripheries of the teeth when being supplied with electricity. The magnetic poles being switched by controlling electricity supplied to the plurality of coils. A rotator has an outer circumferential periphery opposed to the inner circumferential peripheries. The outer circumferential periphery defines magnetic poles different from each other with respect to a rotative direction thereof. A pump portion that has a rotor member rotated by the rotator for pumping fuel. An electrically insulative resin material is charged between the teeth, which are circumferentially adjacent to each other, thereby being molded such that the electrically insulative resin material covers the plurality of coils.
