A

To provide a wing with no flap and with passively variable camber, and an aircraft having this wing.SOLUTION: A wing comprises: a box structure constituting a front edge of the wing; a top face outer plate which is attached to a rear end of a top face of the box structure, has an upper rear end as a free end, and has flexibility; an undersurface outer plate which is attached to a rear end of an undersurface of the box structure, has a lower rear end as a free end, and has flexibility; an upper slide member provided at the upper rear end; and a lower slide member which is provided at the lower rear end, and slidably line contacts the upper slide member in a slide direction including a wing chord component, whereby the top face outer plate and the undersurface outer plate are mutually energized, and which blocks a rear edge of the wing constituted by the upper rear end and the lower rear end. Each length of the upper slide member and the lower slide member in the slide direction is a length such that the upper slide member and the lower slide member can always line contact while displacing a tangent line in the slide direction in association with deformation of the top face outer plate and the undersurface outer plate.SELECTED DRAWING: Figure 2
