The invention relates to the field of buildings, in particular to a decorating plate with high earthquake resistance and a manufacturing method of the decorating plate. The manufacturing method comprises the following steps that a first metal keel and a first inorganic plate opposite to the first metal keel are fixed to a main structure; a plurality of screw rods sequentially penetrate through thefirst metal keel and the first inorganic plate and are fixed to the first metal keel and the first inorganic plate, wherein the screw rod located at the main structure sequentially penetrates throughthe first metal keel and the main structure and is fixed to the first metal keel and the main structure; an outer wall decorating plate body is mounted and fixed to the outer side of the first metalkeel through a dry hanging piece; and heat-preservation mortar is injected into the space between the outer wall decorating plate body and the first inorganic plate. The decorating plate with the highearthquake resistance and the manufacturing method of the decorating plate are safe, reliable and stable, the earthquake resistance property of a building is improved, the weight of the building is decreased, the field assembly speed is high, and thus the mounting period of the building can be shortened; and decoration, heat preservation and a wall body are integrated, thus the wall body does notneed to be built again, the cost performance is high, and the decorating effect is good.
