PROBLEM TO BE SOLVED: To provide a furnace bottom structure of a bottom-blow converter, which does not make a tuyere deformed due to the expansion of a bottom brick even when a distance between the tuyeres is shortened, and makes a joint of the brick between the tuyeres hardly eroded, in order to solve problems of a furnace bottom structure of a conventional bottom-blow converter. SOLUTION: The furnace bottom structure of the bottom-blow converter is formed of a plurality of brick lines arranged in parallel, and has a plurality of tuyere bricks (11) for retaining a tuyere pipe (14) arranged in one particular brick line along a diameter of the furnace bottom among the brick lines (12), and has one plate of brick (12) for the tuyere bricks exist in between the tuyere bricks, when the tuyere bricks (11) are arranged.
