SOLUTION: In the square-wave molded plate 1 composed of ridge strip sections 3 having a trapezoidal shape in a cross-section view formed at fixed intervals in the cross direction and plate sections 4 in comparatively broad width in the cross direction, projecting sections 2 having a triangular shape in a longitudinal-section view extended along the cross direction are formed in the plate sections 4.
