A method for pouring a melt using a bottom-pouring-type ladle comprising a melt-pouring nozzle and a stopper rod, comprises an opening step, in which the stopper rod is separate from the nozzle; a first closing step, in which the stopper rod moves downward, such that a lower end portion of the stopper rod comes into contact with a tapered surface of the nozzle when the horizontal distance between their center axes becomes 2 mm or more; and a second closing step, in which a lower end portion of the stopper rod further moves downward along the tapered surface of the nozzle to close the nozzle.
