The carrier part includes passage bores, through which the bristle bundle and resiliently soft cleaning element project, and each is fixed to the carrier part by way of a thickened portion formed by a filament material or a resiliently elastic material, respectively. A method of producing a brush head is also provided, including preparing the carrier part as a separate component with passage bores, fixing the bristle bundle and the resiliently clastic cleaning element to the carrier part with a thickened portion provided on the bristle bundle and the resiliently elastic cleaning element, respectively, and connecting the carrier part to the holding part.
