A coil for a motor includes a coil which is formed of a conductor wound around an axis; and a plurality of cooling portions which are provided to correspond to different winding layers in the conductor. Each of the cooling portions includes a primary portion protruding from the winding layer radially outward and a secondary portion extending from a tip of the primary portion toward a first side in a direction of the axis. The primary portions are formed so that the protrusion length of one of the primary portions, which is located closer to a second side in the direction of the axis than another of the primary portions, is longer than that of the another of the primary portions.

A lateral orientation type of anisotropic permanent magnet having a face of magnetic application and at least one lateral face adjacent to the face of magnetic application. An axis of easy magnetization of particles of a magnetic powder constituting the permanent magnet is oriented substantially along lines from the lateral face toward the face of magnetic application to increase the peak value of the surface magnetic flux density at the face of magnetic application.
