Provided is a wing the weight of which can be reduced, with consideration given to stress concentrations in areas around access holes. A wing (1) on which a tensile load is imposed in the longitudinal direction is provided with a center section (3b), a forward section (3a), and an aft section (3c). The center section (3b) is a holed structural member that is a fiber reinforced plastic composite material article which extends in the longitudinal direction and in which access holes (5) are formed. The forward section (3a) and the aft section (3c) are reinforced plastic composite material articles that extend in the longitudinal direction of the wing (1) and are connected to the sides of the center section (3b). The tensile stiffness of the center section (3b) in the longitudinal direction is lower than the tensile stiffness of the forward section (3a) and the aft section (3c) in the longitudinal direction.
