Abstract
A stator includes a yoke extending to surround an axis, and having an outer circumference and an inner circumference. The yoke has a crimping portion projecting from the outer circumference, and a split surface provided at a position different from a position of the crimping portion. The yoke has a magnetic path which is provided between the outer circumference and the inner circumference and through which magnetic flux flows. When L1 represents the width of the magnetic path, and L2 represents the width of the yoke including the crimping portion, L1<L2<2.6×L1 is satisfied.
