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 u_<yh>. Then from this formulation, the stress behavior for side plates was discussed. Normal stresses σ_x and σ_y 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 τ_<xy> is antisymmetric. Maximum σ_<x max> of |σ_x| is at centers of side plates and maximum |σ_<ymin>|of|σ_y| is about at corners. And maximum τ_<xy max> of |τ_<xy>| is at distance L/16 from corners in upper and lower edges. Ratios σ_<x max>/|σ_<ymin>| and τ_<xy max>/|σ_<y min>| are about 0.14 and 1.13.
