A razor head, comprising: a frame; elongated blades arranged on an inner side of the frame; and two bridge walls (24, 25) each extending between two points of the frame in an interior of the frame, the bridge walls (24, 25) each including projections arranged in an arrangement direction of the blades, wherein each of the blades is held between adjacent ones of the projections of the bridge walls (24, 25), characterised in that: each projection has a horizontal cross-sectional shape of a parallelogram, wherein each of the projections includes: a first flat surface that is in contact with the blade located on one side of the projection in the arrangement direction; a second flat surface that is in contact with the blade located on the other side of the projection in the arrangement direction; and a third flat surface and a fourth flat surface that are inclined with respect to the first flat surface and the second flat surface, the first flat surface is parallel to the second flat surface, the third flat surface is parallel to the fourth flat surface, in each of the bridge walls (24, 25), the first flat surface and the second flat surface are shifted from each other in a longitudinal direction of the blades so as not to overlap each other as viewed in the arrangement direction, and the first flat surfaces are located on the same position as viewed in the arrangement direction and the second flat surfaces are located on the same position as viewed in the arrangement direction. a frame; elongated blades arranged on an inner side of the frame; and two bridge walls (24, 25) each extending between two points of the frame in an interior of the frame, the bridge walls (24, 25) each including projections arranged in an arrangement direction of the blades, wherein each of the blades is held between adjacent ones of the projections of the bridge walls (24, 25), characterised in that: each projection has a horizontal cross-sectional shape of a parallelogram, wherein each of the projections includes: a first flat surface that is in contact with the blade located on one side of the projection in the arrangement direction; a second flat surface that is in contact with the blade located on the other side of the projection in the arrangement direction; and a third flat surface and a fourth flat surface that are inclined with respect to the first flat surface and the second flat surface, the first flat surface is parallel to the second flat surface, the third flat surface is parallel to the fourth flat surface, in each of the bridge walls (24, 25), the first flat surface and the second flat surface are shifted from each other in a longitudinal direction of the blades so as not to overlap each other as viewed in the arrangement direction, and the first flat surfaces are located on the same position as viewed in the arrangement direction and the second flat surfaces are located on the same position as viewed in the arrangement direction. each projection has a horizontal cross-sectional shape of a parallelogram, wherein each of the projections includes: a first flat surface that is in contact with the blade located on one side of the projection in the arrangement direction; a second flat surface that is in contact with the blade located on the other side of the projection in the arrangement direction; and a third flat surface and a fourth flat surface that are inclined with respect to the first flat surface and the second flat surface, a first flat surface that is in contact with the blade located on one side of the projection in the arrangement direction; a second flat surface that is in contact with the blade located on the other side of the projection in the arrangement direction; and a third flat surface and a fourth flat surface that are inclined with respect to the first flat surface and the second flat surface, the first flat surface is parallel to the second flat surface, the third flat surface is parallel to the fourth flat surface, in each of the bridge walls (24, 25), the first flat surface and the second flat surface are shifted from each other in a longitudinal direction of the blades so as not to overlap each other as viewed in the arrangement direction, and the first flat surfaces are located on the same position as viewed in the arrangement direction and the second flat surfaces are located on the same position as viewed in the arrangement direction. the first flat surface and the second flat surface are shifted from each other in a longitudinal direction of the blades so as not to overlap each other as viewed in the arrangement direction, and the first flat surfaces are located on the same position as viewed in the arrangement direction and the second flat surfaces are located on the same position as viewed in the arrangement direction.
