PROBLEM TO BE SOLVED: To provide three-dimensional interesting design on a decorative face by making one side of a unit waveform in the wave pattern of a constructuon plate having the waveform pattern on a whole or a part of the decorative face a steep inclined face, and making the other side a gentle inclined face. SOLUTION: A construction plate 1 as an outer wall material comprising a wooden reinforcing material mixed inorganic plate arranges the lateral long pattern blocks 3 of the unit waveform shape of arbitrary width and arbitrary length on the arbitrary part of the decorative face in the longitudinal direction of the construction plate 1 in parallel to form a waveform pattern 5. The waveform pattern 5 is intermittently formed in the longitudinal direction of the lateral long pattern block 3 and in the direction orthogonal thereto. Each lateral long pattern block 3 of the unit waveform shape makes one side, in which it is divided into two parts along the longitudinal direction, a steep inclined face 31 and makes the other side a gentle inclined face 32. The surface of each lateral long pattern block 3 is provided with the small recess and projection of natural stone tone, a part except for the lateral long pattern block 3 of the decorative face is provided with the slightly large recess and projection of the natural stone tone, and a shading appears by the steep inclined face 31 and the gentle inclined face 32 to emphasize a three-dimensional feeling.
