Abstract: Provided is a high-frequency induction melting furnace which decreases a loss along a total length of a coil, so that a heating efficiency can further be improved. An energization coil 3 is wound around an outer periphery of a melting chamber 2 so that tube body spaces a, b of both end portion regions H, L having predetermined numbers of turns from feeding terminals 33, 34, respectively, are larger than a tube body space c of an central portion region S positioned between the both end portion regions H and L. A tube body 32 constituting the energization coil 3 is formed so that in a cross section perpendicular to an axial line of a longitudinal direction of the tube body, an outer peripheral shape and an inner peripheral shape which is a water flow path 31 are both rectangular.
