The present invention relates to a rotorcraft blade (P) provided in succession with a radial segment ( 1 ) and then a swept segment ( 2 ), said swept segment ( 2 ) being provided with at least one forwardly-swept segment ( 2 ') and/or rearwardly-swept segment ( 2 ''). In addition, the blade has a single spar coming from the blade root. The invention is remarkable in that the single spar comprises a radial spar ( 10 ) in the radial segment ( 1 ), after which the single spar splits where the radial segment ( 1 ) becomes the swept segment ( 2 ) to form thereafter in the swept segment ( 2 ) a primary spar ( 11 ) and a secondary spar ( 12 ).
