The present invention prevents the occurrence of cracks in the neck section of a submerged nozzle that is applied to a submerged nozzle exchange device. To this end, a submerged nozzle (10) is configured from a nozzle main body section (11), a flange section (12), and a metal case (13), the outer peripheral surface of the nozzle main body (11) extends to the upper end in the vertical direction above a leverage section (P) for upward support force resulting from a support member (20) without causing any change in the size of an inner hole (11a) with respect to a central axis (C), and said outer peripheral surface is shaped so as not to have a surface that engages with the metal case (13). |
