There is provided a novel construction of a metal melting furnace that can preheat and melt the entire material more efficiently and that can facilitate operations for removing oxides deposited on the surface around the melting burner and the inside thereof and thus reduce the time for cleaning the inside of the furnace. The metal melting furnace 10 includes a melting chamber 20 that has a material charging port 21 and a flue 22 at the top and a hearth section 25 along which melted material flows down to a molten material holding section 60 at the bottom, wherein a combustion chamber 30 equipped with a melting burner 35 is formed below the hearth section 25 , a heating plate 40 comprised of a heat-resistant plate having high heat conductivity is disposed in the hearth section 25 above the combustion chamber 30 , and an exhaust gas outflow passage 50 from the combustion chamber 30 is formed in a side wall of the melting chamber 20.
