An embodiment relates to a stator and a motor comprising same, the stator comprising: a stator core comprising a yoke and multiple teeth protruding from the inner surface of the yoke; an insulator surrounding a part of the stator core; a coil wound around the insulator; and a molding portion disposed to cover the stator core, the insulator, and the coil. The insulator comprises a first insulator and a second insulator. The first insulator comprises: a body portion around which the coil is wound; and inner guide extending from the inside of the body portion in the perpendicular direction; a first outer guide extending from the outside of the body portion in the perpendicular direction; a second outer guide disposed to be spaced apart from the first outer guide in the outward direction; and a protrusion protruding from the second outer guide in the inward direction. The protrusion has an end portion disposed such that a predetermined gap (G) is formed between same and the first outer guide. The coil has a part disposed between the first outer guide and the second outer guide through the gap (G). Accordingly, it is possible to inhibit the coil from contacting the housing due to injection molding pressure during over-molding of the stator.
