The invention relates to an aircraft propeller blade including a structure having an airfoil, consisting of at least one fibrous reinforcement (200) obtained by three-dimensional weaving of threads and made denser by a matrix and a spar (60) including a bulged portion (62) extending outside of the fibrous reinforcement and forming the shank of the blade, and a shaped portion (61) in a recess (206) provided within the fibrous reinforcement (200). The fibrous reinforcement (200) comprises a disconnection area (204) forming the recess (206) inside the fibrous reinforcement (200). The disconnection area (204) leads to the lower portion (220) and the rear edge (230) of the fibrous reinforcement (200) such as to form an opening (231) for inserting the shaped portion (61) of the spar (60) into the recess (206) of the fibrous reinforcement. The opening (231) on the rear edge (230) of the fibrous reinforcement (200) extends over a height (H231) that is shorter than the height (H204) of the recess such as to provide, on said rear edge (230), a retaining portion (232) that is at least partially in contact with the shaped portion (61) of the spar (60).
