The invention aims to make it possible to efficiently produce an ingot, by efficiently cooling an ingot that is removed from a mold built into a melting furnace for smelting metal, in the production of active metal using the melting furnace, which has a hearth. Also, the invention provides a device configuration whereby a plurality of ingots can be produced from one hearth efficiently and with consistently high quality. This melting furnace for smelting metal comprises: a hearth for retaining molten metal produced by melting a raw material; a mold into which the molten metal is loaded; a drawing jig for downwardly drawing a cooled and solidified ingot, the drawing jig being provided below the mold; a cooling member for cooling the ingot; and an outer tube for separating the hearth, mold, drawing jig, and cooling member from the atmosphere, wherein at least one mold and the drawing jig are disposed within the outer tube, and the cooling member is disposed between the outer tube and the ingot or between a plurality of the ingots.
