Abstract: Provided is an electric water pump with an over-molding stator for improving a flow structure and a dimensional accuracy in the water pump. The pump largely includes: a stator including a rotor accommodation part accommodating a rotor and a plurality of coils arranged around a rotating shaft of the rotor in a circumferential direction; and a molding part surrounding the stator to insulate the plurality of coils, wherein the molding part is injected onto the stator to surround the entire coil while having a plurality of flow paths formed between the coils and passing through in a direction of the rotating shaft.
