A method of elastic analysis is studied for double walled corrugated fiberboard (DWCF) of symmetrical shape (to the machine direction) under uniform bending of the moment axis perpendicular to the machine direction. Then this method is applied to stress analyses for several shapes of DWCF. The following results are obtained. (1) Deformations of kraftliner (KL) and corrugated medium (CM) in DWCF under the uniform bending are expressed as the sum of simple tensioncompression and uniform bending. (2) Maximum stresses σ_<klmax> and σ_<slmax> for KL and CM on the upper side are equal to σ_<klmax> and σ_<slmax> on the lower side. σ_<klmax> is on the outer surface, and σ_<slmax> is at the KL (middle KL)・CM joint on the inner surface. (3) σ_<slmax> increases with the increase of the wavelength and the thickness, and decreases with the increase of the height for CM.
