To provide a brush supporting member that makes it possible to cut cost by simplifying a metal mold structure and molding processes in insert molding for fixing metal bracket plates and feeding brushes to one another integrally via an insulating resin.

The metal bracket plates 21 and feeding brushes 22 are fixed to one another integrally by the insert molding via the insulating resin that constitutes a resin mold 23. Free ends of the feeding brushes 22 are arranged at the side in the plate surface 21d direction of the metal bracket plates 21 to the fixed end, and moving portions of the feeding brushes 22 are arranged in a region facing plate surfaces 21d of the metal bracket plates 21. Regions facing the moving portions of the feeding brushes 22 at the plate surfaces 21d of the metal bracket plates 21 are disposed without being covered by a resin molded portion 23.
