Zusammenfassung:	PROBLEM TO BE SOLVED: To efficiently mass-produce a carbonaceous microfibrous material having a homogeneous shape and physical properties at a low cost by preventing solidification of the carbonaceous microfibrous material in a reactor or a pipe when the carbonaceous microfibrous material is produced by reacting a carbon source gas in the presence of a catalyst in the reactor. SOLUTION: Catalyst particles and the carbon source gas are introduced into a spouted-bed reactor 30 to produce aggregate having 10-200 μm average particle diameter of the carbonaceous microfibrous material while forming a spouted bed. The aggregate particles and the carbon source gas are introduced into fluidized bed reactors 40 and 50 to grow the aggregate while forming a fluidized bed of the aggregate.Thereby, the carbonaceous microfibrous material is produced.
