PROBLEM TO BE SOLVED: To provide a manufacturing method for artificial marble which has the stereoscopic vision and a texture of natural granite and a pattern with deep colors, exhibits an upscale image, enables the formation of an appearance with both a grain pattern and a stripe pattern, and facilitates the control of the patterns. SOLUTION: This manufacturing method comprises the following processes: a curable composition (A) 2 containing resin particles of 0.5-30 mass%, which are 0.1-5.0 mm in diameters, is injected into a molding cell; at least one layer of a curable composition (B) 3 different in color from the composition (A) 2 is laminated on the injected composition (A) 2 in a layered manner; and the laminated compositions (A) 2 and (B) 3 are cured after a comb-shaped member 1 is moved in the compositions (A) 2 and (B) 3 while the teeth of the member 1 are brought into contact with the bottom surface of the molding cell.
