A small electric motor having an insulating cylinder fixedly fitted to a rotating shaft of a motor rotor, a plurality of commutator segments disposed at equal spacing in the angular positional direction of the insulating cylinder and brushes for making sliding contact with the cummutator segments. Each of the commutator segments has a commutator terminal formed by bending an end of the segment and led out for external connection. The insulating cylinder has an enlarged diameter portion, on which adhesive reservoirs are provided. An electrically conductive adhesive is injected into the reservoirs and deposited in such a manner as to bridge the adjoining commutator segments.
