Classification: CPC H  F | IPC F  H

Claim 0:
1. A stator comprising:
a first core that includes a first tooth extending in a first radial direction and a first core back extending in a circumferential direction; and
a second core that includes a second tooth extending in a second radial direction and a second core back extending in the circumferential direction and connects with the first core, wherein
the first core back includes:
a depression formed with at least a first face and a second face in an outer peripheral surface of the first core back; and
a connection part facing the second core back,

the stator satisfies θ1<θ2 and α1≤θ1<90 degrees where
θ1 represents an angle between the first face and the first radial direction in a plane perpendicular to an axial direction,
θ2 represents an angle between the second face and the first radial direction in the plane, and
α1 (degrees) represents an angle between the connection part and the first radial direction in the plane, and

the second face of the depression is formed at a position where a straight line passes through a center of the first tooth in the first radial direction in the plane.
