PROBLEM TO BE SOLVED: To provide a method and apparatus for producing a carbon nanofiber by a fluidized bed method. SOLUTION: The apparatus for producing the carbon nanofiber 22 has a fluidized bed reaction part 12 having a fluidized material charged in the interior, a raw material-feeding means 14 for feeding a carbon raw material 13 into the fluidized bed reaction part 12, a catalyst-feeding means 16 for feeding a catalytic metal 15 into the fluidized bed reaction part 12, a free boarded part 17 having a space in which the fluidized material 11 in the fluidized bed reaction part 12 is scattered and flows down, a fluidizing gas-feeding means 19 for feeding a fluidizing gas 18 to be introduced to the fluidized bed reaction part 12 and for fluidizing the fluidized material 11 in the interior, a heating means 20 for heating the fluidized bed reaction part 12, a CO-feeding means 21 for feeding CO into the fluidized bed reaction part 12, a recovery line 23 for recovering the carbon nanofiber 22 and the fluidized material 11 scattered from the free boarded part 17, and a separation means 24 for separating the fluidized material 11 and the carbon nanofiber 22 recovered at the recovery line 23.
