PROBLEM TO BE SOLVED: To provide a molten metal feeding apparatus which stably regulates the flow rate of the molten metal, and suppresses the leakage of the molten metal in the closing state. SOLUTION: The molten metal feeding apparatus comprises a reservoir 7 for storing the molten metal 4, an outlet 8 for outside delivering and feeding the molten metal 4 in the reservoir 7, and a flow rate controller 12 provided downstream of the reservoir 7 and upstream of the outlet 8 for controlling the flow rate of the molten metal 4 delivered from the outlet 8. The flow rate controller 12 is constituted separately of a flow rate regulating part 10 for regulating the flow rate of the molten metal 4 delivered from the outlet 8, and an opening/closing controller 11 provided downstream of the flow rate regulating part 10 for switching between the opening state of allowing for the delivering of the molten metal 4 from the outlet 8 and the closing state of stopping it.
