Stator and rotary electric machine

A stator, comprising:

• a stator core including a yoke having an annular shape, and teeth protruding from the yoke to an inside of the yoke;
• a first insulator covering at least a first part of the stator core and a part of a first tooth of the teeth;
• a second insulator covering at least a second part of the stator core and a part of a second tooth of the teeth adjacent to the first tooth;
• a first coil disposed around the first tooth via the first insulator;
• and a second coil disposed around the second tooth via the second insulator, wherein each of the first insulator and the second insulator includes a first face facing a corresponding one of the first coil and second coil, and a second face facing the yoke, the first face being perpendicular to a protrusion direction of the teeth, the second face including a first perpendicular face perpendicular to the protrusion direction of the teeth, and a first inclined face inclined toward the first face with respect to the first perpendicular face, and wherein the yoke includes an inner circumferential face facing the second face, and the first insulator is directly adjacent to the second insulator.
