The immersion nozzle includes a nozzle body, a flange, and a metal casing. The nozzle body is formed such that a region of an outer peripheral surface thereof located above a point of power of an upward supporting force from a supporting device extends vertically up to an upper edge of the nozzle body without any dimensional change with respect to an central axis of an inner bore of the nozzle body. The outer peripheral surface region is not joined to the metal casing.
