PROBLEM TO BE SOLVED: To provide a control panel for growing artificial quartz, which has a large practical region, is capable of being easily separated from a grown artificial quartz and obtains a high quality artificial quartz, a method of manufacturing the artificial quartz using the control panel and the artificial quartz by the method. SOLUTION: In the manufacture of the artificial quartz by attaching the control panel having a side wall to the upper surface of a seed quartz and carrying out a hydrothermal synthetic method using heat convection, the angle between the control panel main body and the side wall is controlled to make an acute angle and a projected part or a projected line is provided on the side wall.
