Abstract
A structure of a panel includes a peripheral portion and an intermediate portion integrally provided with the peripheral portion. At least the intermediate portion includes a curved surface having a substantially constant sum of the maximum curvature and the minimum curvature at all the points on a surface of the intermediate portion. Further, the peripheral portion is formed as the same curved surface as the curved surface of the intermediate portion, or a curved surface having a curvature different from the curvature of the curved surface of the intermediate portion so as to enhance the panel stiffness of the peripheral portion.
