PURPOSE: To prevent generation of a crack in a ceramic member installed in the casting space of a casting mold without the need for heating the mold by embedding the ceramic member by casting in the state of preheating the member by the heat of the molten metal passed near the casting space.

CONSTITUTION: The molten metal poured through a pouring port 2 passes through a runner 3 formed near a casting space 5. The molten metal 9 heats consequently the ceramic member 8 installed in the space 5 and fills the inside of a well 4 and thereafter the molten metal past a runner 6 flows into the space 5 and embeds the member 8 by casting. The heat of the molten metal 9 in the well 4 is transmitted through a casting mold 1 to the member 8 and preheats the member 8 during the time when the metal 9 flows into the space 5.
