A rotating electrical machine includes a magnetic field-producing unit and an armature. A magnet unit is equipped with a plurality of magnets arranged adjacent each other in a circumferential direction. Each of the magnets is magnetically oriented to have an easy axis of magnetization which is aligned near a d-axis that is defined on a center of the magnetic pole to be more parallel to the d-axis than an easy axis of magnetization near a q-axis that is defined on a boundary between the magnetic poles. An armature winding includes conductive members which face the magnetic field-producing unit and are arranged at a given interval away from each other in the circumferential direction. Each of the magnets has an end surface which faces in the circumferential direction and is placed in direct contact with an end surface of a circumferentially adjacent one of the magnets.
