There is provided a wing panel having improved formability at the time when the wing panel is curvedly formed by the peen forming method, and an aircraft main wing provided with the said wing panel. For a stringer member 20, a base part 21 is formed, and the neutral axis position N in the cross-sectional direction is located on the wing panel 11 side from the center position C in the height direction of a web part 22. When the peen forming method is carried out by projecting metal shots to a portion near a flange part 23 in the tip end portion of the stringer member 20, the tensile strain developing in the portion near a flange part 23 acts in a state in which the moment length around the neutral axis position N is kept long. As a result, the compressive strain developing in the base part 21 and the wing panel 11 is in inverse proportion to the moment length around the neutral axis position N so as to attempt to balance with the tensile strain, so that the wing panel 11 is deformed at a small radius of curvature.
