PROBLEM TO BE SOLVED: To provide a manufacturing method for a crucible and a semiconductor ingot for solving a problem wherein silicon melted liquid in the crucible is supplied into a mold while temperature of the silicon melted liquid is raised beyond necessity. SOLUTION: This crucible has a liquid drain port for draining semiconductor melted liquid, and the liquid drain port is closed by a plug body made of the same component as the semiconductor melted liquid and is opened by destroying the plug body by a destruction means.
