Abstract: The object of the present invention is to provide a needle coke for a graphite electrode, which suppresses puffing of the needle coke and improves the production yield and performances of graphite electrodes without incurring a large cost in the production of a needle coke, and also provide a production method and an inhibitor therefor. An inhibitor for graphite electrode production, including at least one of a metal consisting of an element (Mβ) and an oxide comprising the element (Mβ), wherein the element (Mβ) is at least one element selected from the group consisting of group 4 elements, group 8 elements, group 9 elements, group 10 elements, group 13 elements, group 14 elements and group 15 elements of the long-form periodic table, or including at least one of the metal consisting of an element (Mβ) and a compound including the element (Mβ), wherein the inhibitor volatilizes at a temperature of 2100 to 6000° C.
