PROBLEM TO BE SOLVED: To provide a tundish for continuous casting in which the floatation separation of inclusions therein is further promoted to reduce the amount of molten steel remaining in the tundish at the last stage of the use of the tundish as much as possible. SOLUTION: Each crossed part between the bottom part and both the side faces in the width direction of a tundish is provided with a tilted part having a climbing tilt from the molten steel inlet part of the tundish toward the direction of an outlet side injection nozzle, the length L in the longitudinal direction of the tundish in the tilted part is controlled to 1 m to L<SB>0</SB>-1 m, the distance L<SB>n</SB>from the center of the molten steel inlet part of the tundish to the tilt starting position of the tilted part is controlled to 0.5 to 1 m, the maximum climbing height H of the tilted part is controlled to 0.1×H<SB>0</SB>to 0.5×H<SB>0</SB>, and the distance W<SB>n</SB>between the two tilted parts is controlled to≤0.2 m; wherein, L<SB>0</SB>denotes the distance (m) from the center of the molten steel inlet part 5 of the tundish to the center of the outlet side injection nozzle 6; and H<SB>0</SB>denotes the maximum molten steel height (m) in the tundish.
