PROBLEM TO BE SOLVED: To provide a crucible furnace that can smoothly perform production activity such as stable operation quickly and securely without causing any unexpected failure by eliminating highly hazardous, hard and dirty operations of furnace wall maintenance work of a crucible furnace being used for melting and/or refining nonferrous metals, and at the same time by improving durable life. SOLUTION: An inner lining material is composed of an operation layer part and a void layer part. The outer-layer part is composed by a furnace body part that is composed by a furnace shell iron skin part or at least a layer of refractory or heat-insulating material inside. Then, a burner tile 3, a slag discharge port 10, a site material for measuring temperature, and the like are fixed at the specific site of a furnace for constructing the furnace with the burner tile 3, the slag discharge port 10, and a part for excluding a point for loading the material for measuring temperature as needed as a one-piece refractory.
