PROBLEM TO BE SOLVED: To provide a manufacturing method of artificial marble reduced in molding strain or warpage by preventing air bubbles from remaining in a resin molded product when the molded product is manufactured using a casting mold. SOLUTION: A resin composition 7 is prepared by compounding additives such as a filler, an internal mold release agent, a curing agent, a pattern material for expressing an artificial marble pattern, etc., with a thermosetting resin. This resin composition 7 is injected in an injection space 4 from the injection port 2 of the casting mold 1 and cured under heating to manufacture the artificial marble. In this manufacturing method of the artificial marble, the resin composition 7 is injected in the injection space part 4 from the injection port 2 while applying vibration to the resin composition 7.
