1. A stator comprising:
a stator core including an annular yoke, and a plurality of teeth each extending from an inner periphery of the yoke in a radial direction and arranged in a circumferential direction of the yoke at intervals, in which a gap between a pair of teeth adjacent to each other in the circumferential direction forms a slot extending in the radial direction, and with respect to the pair of teeth and the slot, only one tooth of the pair of teeth including a convex holder-shaped part which is provided at a position apart from a distal end surface of the teeth outward in the radial direction, projects in the slot toward the other tooth, and extends in an axial direction of the yoke; and
a stator coil wound around the stator core, the stator coil including a plurality of linear conductors aligned in the radial direction in the slot and held in the slot by the convex holder-shaped part.
