This patent describes a starting pitch for producing carbon fiber. This pitch essentially consists of a mixture of (a) 100 parts by weight of a petroleum pitch and (b) 5 to 500 parts by weight of a methanol-insoluble and benzene-soluble component contained in a heavy oil obtained in a fluid catalytic cracking of petroleum. The heavy oil has a boiling range not lower than 200/sup 0/C. The component has been obtained by treating the heavy oil with methanol and benzene so as to remove methanol soluble and benzene insoluble fractions therefrom while retaining therein methanol-insoluble and benzene-soluble fractions.
