1. A stiffened panel structure comprising:
a panel-shaped component including a panel body that curves in such a manner as to be convex outward; and
a wire having a first end portion and a second end portion, the first end portion being bonded to a first point on an inner surface of an area of the panel body excluding lateral edges of the panel-shaped component by an adhesive and the second end portion being bonded to a second point on the inner surface of the area of the panel body excluding the lateral edges by the adhesive in such a manner that the wire is strained between the first point and the second point,
wherein:
the panel body includes:
an expected load point onto which a load is expected to be applied from outside; and
a first area and a second area that, without the wire, are expected to be displaced in directions opposite to a loading direction and away from the expected load point when a load is applied to the expected load point from outside;
the second area is opposed to the first area with the expected load point in between; and
the first point is in the first area, and the second point is in the second area.
