An arc furnace includes: a body (1) to be charged with material (S) to be melted; a roof (4) closing an upper opening of the body (1); an arc electrode (5) inserted into the body (1) from above the roof (4) and energized to form electric arcs to melt the material; and an exhaust port (6), through which exhaust gas in the body (1) is discharged, wherein: the arc electrode (5) is arranged so that the center of arc heating is laterally offset from the center of the body in a horizontal plane with respect to the body (1); the exhaust port (6) is provided in a side wall of the body (1) on a side opposite to the offset direction of the arc electrode (5) at a height below the level of presence of the material (S); and the exhaust gas produced by the arc heating by the arc electrode (5) is discharged from the exhaust port (6) through the material (S) in the body (1). |
