Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a secondary cooling apparatus and a secondary cooling method for continuous casting that improve productivity without increasing costs.SOLUTION: A secondary cooling apparatus includes: rollers 2 arranged side by side in a vertical direction along a casting direction; and injection nozzles 3 for injecting cooling water W on a cast slab surface 41 from between the rollers 2. The injection nozzles 3 are disposed such that a crossing position Q1 of the cast slab surface 41 and a cooling water injection axis line J1 of an injection nozzle 3 is positioned above an intermediate position 44 of a position 42 contacting a roller 2 above the injection nozzle 3 and a position 43 contacting a roller 2 below the injection nozzle.SELECTED DRAWING: Figure 3 【課題】コスト上昇を招くことなく生産性の向上を図れる連続鋳造の二次冷却装置および二次冷却方法を提供すること。【解決手段】二次冷却装置は、鋳造方向に沿う上下方向に並んで配置されたロール２と、ロール２の間から鋳片表面４１に冷却水Ｗを噴射する噴射ノズル３とを備え、噴射ノズル３は、鋳片表面４１と当該噴射ノズル３の冷却水噴射軸線Ｊ１との交差位置Ｑ１が、当該噴射ノズル３の上方のロール２との接触位置４２と下方のロール２との接触位置４３の中間位置４４よりも上方に位置するように設けられている。【選択図】図３
