An elastic stress formulation was expressed for side plates in the case of the corrugated fiberboard box shape (CFBS) supported by upper and lower edges under uniform compression loading, and the deformation continuity of neighbouring plates in side edges was considered by this expression. Then from this formulation, characteristic behaviors of stresses and strains were discussed, and the validity of the formulation was denoted by calculation results. Normal stresses and strains ε_<xi>, ε_<yi> in width (L_i: i = 1,2) and height directions for the plate are symmetric to center lines of the width and the height, and shear stress is antisymmetric. And ε_<xi> positive andε_<yi> negative, and the maximum of ε_<xi> is at the center in the side plate and the maximum of ε_<yi> is in the upper or the lower edge in the side. The maximum value of ε_<xi> is about 1/8 to maximum value of |ε_<yi> |. ε_<x1> , ε_<y1> and shear strain γ_<xy1> in the side edge are equal to ε_<x2>, ε_<y2> and γ_<xy2> in its side edge of the neighbouring plate, and bending deformation in the side edge is equal to bending deformation in its side edge in the neighbouring plate, and the deformation is continuous in side edges.
