The bristle planting plate comprises a bristle planting surface and a back surface arranged opposite to each other, and further comprises a circumferential surface located between the bristle planting surface and the back surface. Bristles extend from the bristle planting surface. The back plate is arranged on the side of the bristle planting plate opposite to the bristles. A part of the back plate is spaced apart from the back surface to form a filling groove. The back plate comprises a first connecting end relatively proximal to the brush rod and a second connecting end relatively distal to the brush rod. The back plate is connected with the bristle planting plate by means of the first connecting end and/or the second connecting end. The soft rubber piece is arranged in the filling groove, and covers at least part of the circumferential surface of the back plate and the bristle planting plate. By means of arranging the soft rubber piece, the brush head has good cushioning performance. The soft rubber piece is firmly connected with the brush plate and is not prone to falling off from the brush plate.
