PROBLEM TO BE SOLVED: To obtain an ALC panel superior in the appearance quality capable of uniformly decreasing fine unevenness due to scuffing by uniformly pressing a surface of the ALC panel. SOLUTION: A manufacturing method of the ALC panel includes a process of pressing a roller 20 to the surface 11 having the fine unevenness 13 of the ALC panel 10 after steam curing and pressing the surface 11 of the ALC panel with a width shorter than the width W of the ALC panel 10 to form a consolidation surface. In the pressing process, biting depth of the roller 20 from the protrusion tip of the fine unevenness 13 to the ALC panel 10 is set to be not less than 0.1 mm and less than 1.0 mm.
