To restrict interaction between a discharge flow and an agitation flow, even when a position in a casting direction of a discharge port of an immersion nozzle and a position in a casting direction of the electromagnetic agitation device overlap.SOLUTION: Iron cores 241, 242 are constituted to include a second region where a casting width direction (an X-axis direction) is a longer direction and a first region where the length in the casting width direction is shorter than that in the second region. A range in the casting width direction of the second region contains a range in the casting width direction of the first region. A range in the casting width direction (the X-axis direction) of the first region contains a range in a casting width direction of an immersion nozzle 230. A range where a range in a casting direction (a Z-axis direction) of the second region overlaps with a range in a casting direction in which a discharge flow from discharge ports 230a, 230b of the immersion nozzle 230 flows is shorter than a range where a range in a casting direction of the first region overlaps with the range in the casting direction in which the discharge flow from the discharge ports 230a, 230b of the immersion nozzle 230 flows.SELECTED DRAWING: Figure 6 【課題】 浸漬ノズルの吐出口の鋳造方向の位置と電磁撹拌装置の鋳造方向の位置とが重複する場合でも、吐出流と撹拌流との干渉を抑制することができるようにする。【解決手段】 鋳造幅方向（Ｘ軸方向）を長手方向とする第２の領域と、第２の領域よりも鋳造幅方向の長さが短い第１の領域とを有するように鉄心２４１、２４２を構成する。第２の領域の鋳造幅方向の範囲は、第１の領域の鋳造幅方向の範囲を含む。第１の領域の鋳造幅方向（Ｘ軸方向）の範囲は、浸漬ノズル２３０の鋳造幅方向の範囲を含む。第２の領域の鋳造方向（Ｚ軸方向）の範囲と浸漬ノズル２３０の吐出口２３０ａ、２３０ｂからの吐出流が流れる鋳造方向の範囲とが重複する範囲の方が、第１の領域の鋳造方向の範囲と浸漬ノズル２３０の吐出口２３０ａ、２３０ｂからの吐出流が流れる鋳造方向の範囲とが重複する範囲よりも短い。【選択図】 図６
