An aircraft part (such as a T-shaped member (21), a convex member (22), a curved member (23), or the like) includes: a laminated structure formed by laminating a plurality of composite-material layers; and as a three-dimensional structure, at least one of a standing portion (20b), a convex portion (20c), or a curved portion (20d). The plurality of composite-material layers include at least a composite-material layer in which a reinforced fiber is a single continuous fiber not including a joint portion and includes a partial slit portion (12a). When the thickness of a flat-plate formed body (11) including the same laminated structure as the aircraft part but not including the three-dimensional structure is regarded as a reference thickness, the aircraft part includes a thin plate portion which has a thickness smaller than the reference thickness while maintaining the laminated structure, and the reinforced fiber further includes a notch portion (13b) that is the slit portion (12a) in an open state.
