A rotorcraft blade is provided with a rigid attachment filler (1) and with a spar (40) that extends from a root (51) of the blade to a free end (52) of the blade, the attachment filler (1) having top, bottom, front, rear, left side, and right side faces (2, 3, 4, 5, 7, and 6). The spar (40) then includes a succession of fiber layers (31, 32, 33) that hold the attachment filler (1) captive at the root (51) of the blade, the spar (40) being secured to the top, bottom, front, rear, and left side faces (2, 3, 4, 5, and 7) of the attachment filler (1). |
