For fundamental deformation of the case of the corrugated fiberboard box shape under uniform compression(1N/mm^2), it was discussed that side plate deformation of its case was simulated as the zero displacement of the breadth direction on upper and lower edges. Then an elastic stress formulation, for their side plates(breadth L and height h)was expressed. Also, from this formulation, the stress analysis of its plate was performed and its characteristic behavior was done obviously. In the tange y=3h/8〜5h/8(y:diatance from the center in the height direction), the normal stress σ_x in the breadth direction for the plate decreases with the increases of distance(x-L/2)from the plate center in the breadth direction, and in the range y=3h/8〜5h/8, increases roughly. In y=h/2〜3h/4 range, absolute value σ_y of the normal stress in the height direction for the plate decrease roughly with the in crease of(x-L/2), and in range y>3h/4, the constant σ_y appears about the x=L/2. Also, in the range h/2<y≨3h/4, the absolute shear stress t_xy increases initially and next decreases with the increase of(x-L/2), and in the range y>3h/4 becomes inversely.
