Claim 7:
8. A method of manufacturing a rotating electrical machine that comprises:
a field generator that includes a magnet unit, the magnet unit having a plurality of magnetic poles whose polarities are alternately arranged in a circumferential direction of the rotating electrical machine; and
an armature that includes a multi-phase armature winding and a base member to which the multi-phase armature winding is secured, the base member being made of magnetic material, and having:
a hollow cylindrical or a cylindrical shape;
an inner peripheral surface; and
an outer peripheral surface,
one of the field generator and the armature serving as a rotor of the rotating electrical machine,
the multi-phase armature winding comprising a plurality of conductive members that face the field generator and are arrayed at given intervals away from each other in the circumferential direction,
the method comprising:
a first step of covering one of the inner peripheral surface and the outer peripheral surface of the base member with a filmy sheet member made of thermoplastic resin as non-magnetic material; and
a second step of embedding at least a radial part of each of the conductive members into the filmy sheet member to thereby secure the corresponding one of the conductive members to the base member via the filmy sheet member.
