Zusammenfassung:	Provided are a stator capable of substantially preventing a decrease in torque and a rotary electric machine including the stator. A stator (2) includes a stator core (20), an insulator (4), and a coil (5). The stator core (20) includes: a yoke (21) having an annular shape; and teeth (22) protruding from the yoke (21) to the inside of the yoke (21). The insulator (4) covers at least a part of the stator core (20). The insulator (4) includes: a first face (41) facing the coil (5) wound around the teeth (22); and a second face (42) facing the yoke (21). The first face (41) is perpendicular to the protrusion direction of the teeth (22). The second face (42) includes: a first perpendicular face (421) perpendicular to the protrusion direction of the teeth (22); and a first inclined face (422) inclined toward the first face (41) with respect to the first perpendicular face (421). The yoke (21) includes an inner circumferential face (211) facing the second face (42).
