A large and uniform ingot is produced by casting smaller ingots from a melt of a metallic material which may include a high-melting-point active metal such as Ti or a Ti alloy obtained by a cold crucible induction melting method, forming a consumable electrode by using these smaller ingots, re-melting this consumable electrode by a vacuum arc re-melting method, and casting a larger ingot by using the obtained melt.
