Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for efficiently producing carbon black satisfying both of high black degree and good dispersibility and a method for efficiently producing carbon black having small primary particles, small aggregate, small width of aggregate distribution. SOLUTION: This apparatus for producing carbon black has a first reaction zone for forming high-temperature combustion gas stream, a second reaction zone having a choke part for producing carbon black by mixing the resultant high-temperature combustion gas stream with a raw material hydrocarbon and a third reaction zone for stopping the reaction in the downstream of the second reaction zone. In this case, the length of the choke part is >=800 mm and the diameter of the choke part is
