Claim 3:
4. The stator according to claim 1, further comprising:
an insulator insulating the tooth; and
at least one winding wound around the insulator, wherein
the insulator including
a first portion disposed on each of both sides of the tooth, and extending in a direction perpendicular to the radial direction in the plane, and
a second portion insulating the side surface of the yoke and the side surface of the tooth, wherein
the stator satisfies t2>t1
where t1 is a minimum thickness of the second portion in a direction along a straight line passing through a center of the winding abutting against the second portion and a contact point between the second portion and the winding abutting against the second portion in the plane, and t2 is a maximum thickness of the first portion in a direction along a straight line passing through a center of the winding abutting against the first portion and a contact point between the first portion and the winding abutting against the first portion in the plane.
