PURPOSE:To readily obtain a carbon fiber with low joining and entanglement of mutual fibers by pyrolyzing a carbon source compound in the presence of a specified amount of an alkaline(earth) metal element in a pyrolysis zone of the above mentioned carbon source compound. CONSTITUTION:A carbon source compound such as a hydrocarbon compound is pyrolyzed in the presence of an alkaline(earth) metal compound such as potassium or calcium in an amount of 5X10<-5>-3X10<-1>mol/kg per unit weight of the above mentioned carbon source compound in a pyrolysis zone of the above mentioned carbon source compound to provide the objective carbon fiber. |
