PROBLEM TO BE SOLVED: To prevent clogging of piping and a hole, used for adjusting an inner pressure. SOLUTION: A vessel for supplying molten metal is provided with the vessel in which the molten metal can be held, a hatch arranged so as to be openable/ closable at the upper surface part of the vessel and provided with a through-hole for adjusting the inner pressure, through which the inner side communicates with the outer side of the vessel, and a passage which is arranged at the side surface of the vessel and through which the inner side communicates with the outer side and the molten metal is made to flow. For example, the hatch is arranged nearly at the center of the upper surface part of the vessel.
