On deformation condition for displacement zero in the width direction of upper and lower edges, a formulation of elastic stress was expressed for side plates in the case of the corrugated fiberboard box shape (CFBS) supported by upper and lower edges under compression loading as uniform displacement uyh. Then from this formulation, the stress behavior for side plates was discussed.Normal stresses σx and σy in width (L=300mm) and height (h=400mm) directions x and y for the plate are symmetric to center lines of the width and the height, and shear stress τxy is antisymmetric, Maximum σxmax of|σx|is at centers of side plates and maximum|σymin|of|σy|is about at corners. And maximum τxymax of |τxy|is at distance L/16 from corners in upper and lower edges. Ratios σxmax/|σymin|and τxymax/|σymin|are about 0.14 and 1.13.
