PROBLEM TO BE SOLVED: To provide a production method of ferrocoke by dry-distilating a molded material composed of an iron oxide-containing substance and a carbonaceous material-containing substance, by which the ferrocoke having high cold working strength as a strength after dry-distilation and a high post-reaction strength with CO<SB>2</SB>gas can be produced. SOLUTION: The production method of ferrocoke is characterized in that, when a molded material 10 prepared by mixing and molding an iron-containing substance 2 and two or more kinds of carbon-containing substances 1 is dry-distilated by heating to produce ferrocoke 12, a part of the iron-containing substance 2b and a part of the carbon-containing substance 1b are mixed to produce pseudo particles 6 having a high iron content concentration and a lower fluidity of the carbon-containing substance than a mixture 4 of the rest part of the iron-containing substance 2a and the rest part of the carbon-containing substance 1a, then the pseudo particles 6 are mixed with the above mixture 4 and molded into the molded material 10.
