The invention relates to a blade comprising: - a blade body (12) having an aerodynamic profile comprising a first fibrous reinforcement obtained by three-dimensional weaving and comprising a first matrix in which the first fibrous reinforcement is embedded, the blade body part (12) comprising a cavity formed by a disconnection of the first fibrous reinforcement, - a blade root intended to be connected to a mechanism for the variable adjustment of the blade, and - a spar (13) comprising a core (14) made of composite material and two metal casings (21a, 21b) attached to the core (14) on either side of the core (14). The core (14) comprises a first part that extends inside the cavity of the blade body and a second part that forms the blade root. The two metal casings (21a, 21b) which are attached to the core (14) made of composite material extend over the second part and continue to extend over the first part inside the cavity of the blade body (12).
