PURPOSE: A stone panel for plastering and a manufacturing method thereof are provided to reduce manufacturing costs by not requiring an additional cutting process or complex mold structure. CONSTITUTION: Silicon of a gel state is injected into a receiver of a frame. A model with fixed molds is inserted into the receiver. A flexible mold(50) is completed by curing the silicon. The model is separated and the molds are combined with the flexible mold. Mortar is injected into the mold. A panel(20') is completed by curing the mortar and is separated from the flexible mold.
